See “Adding a Connector Interface” on page 38. To produce a trace, press the RUN/STOP hardkey. Run/Stop light Stop measurement. 42 The light behind the RUN/STOP hardkey goes on.
OTDR Mode 1 Getting Started . Figure 8 The Trace Screen Trace • When you have taken a measurement, the graph of the reflected power is displayed as a function of distance. This graph is called the trace. Event Bar • Below the trace, the event bar shows you the position of the detected events: non-reflective events such as splices, reflective events such as connectors, as well as any defined landmarks. You can add and remove the event bar by selecting [View] from the popup panel.
1 Getting Started OTDR Mode Trace Overview • No matter when you zoom to a point of interest on the trace, you do not lose orientation, as there is an overview display in the full-trace window. You always know where you are. The full-trace window is shown in the bottom left-hand corner of the display. In the title bar you can see the name of the measurement file (UNNAMED if you have not already saved the measurement).
OTDR Mode Relative to both markers 1 Getting Started The following parameters are measured between marker A and marker B. The recorded values change when you move either marker. • A-B: the distance between the markers • One of the following (selectable in the [ANALYSIS] menu): – 2pt.L: 2-point loss between the markers. This is the difference in power level between the marker points – 2pt.Attn.: 2-point attenuation. This is the 2-point loss per length unit. – LSA-Attn.: LSA Attenuation.
1 Getting Started OTDR Mode • PWidth: The pulsewidth in seconds (ns or µs), selectable from the [SETTINGS] menu. The available pulse widths are module-dependent. • Optimize: The Optimizing mode. This is the range for measurements, and is selectable from the [SETTINGS] menu. Possible Optimizing modes are – Resolution: for short fibers, – Dynamic: for long fibers, and – Standard: for a compromise between Resolution and Dynamic. If you have specified Automatic measurements, you see Auto Res., Auto Dyn.
OTDR Mode 1 Getting Started Cursor Down • The DOWN key zooms in around the current marker, which stays in the center of the grid. If both markers are highlighted, zooming is performed around the midpoint of the markers. Pressing the DOWN key for a second time restores the full trace. The Cursor key diagram to the right of the trace shows the current mode. If you see a horizontal magnifying glass, you are viewing the whole trace.
1 Getting Started The popup panel The popup panel If you press the SELECT key in OTDR mode. you normally see a popup panel, offering fast access to various menus and important functions. Figure 10 The popup panel The following functions are available in OTDR mode: • [CANCEL] - exit the popup panel and return to normal OTDR mode. • [FILE] menu - File utilities, including loading and storage of data and printing a trace. • [CONFIG] menu - configure the Mini-OTDR.
The popup panel 1 Getting Started • [ANALYSIS] menu - analyze the trace. Use the cursor keys to move to the function you require, and press SELECT again to select it. NOTE If you do not select any option, the popup panel disappears after approximately 10 seconds. When you select [FILE], [CONFIG], [VIEW], [EVENTS], or [ANALYSIS], you see a list of menu options. Use the UP and DOWN cursors to move to the option you want, and press SELECT or RIGHT.
1 Getting Started The Settings screen The Settings screen Select SETTINGS from the popup panel. You see one of the two pages of the Settings screen: Measurement Settings or Pass/Fail Parameters. Change Settings screen Figure 11 Change parameters You switch between the Settings pages by selecting one of the arrows at the bottom left of the Settings screen (Figure 11). Settings page navigation arrows To change a parameter in the settings screen, move to the appropriate box and press SELECT.
The Settings screen 1 Getting Started NOTE Changes made to the settings screen only affect subsequent measurement acquisitions. However, you can apply the changes that you have made to a trace that is currently running by pressing RUN/STOP again. The Measurement Settings screen The Measurement Settings page contains a list of parameters that you can set (Figure 12).
1 Getting Started The Settings screen Wavelength • Wavelength: laser wavelength. This is only meaningful if you have a dual-wavelength OTDR module. The available wavelengths depend on how your module has been configured. Measurement Mode • Meas. Mode: The Measurement Mode: Realtime to update the settings while making a measurement, Averaging to reduce noise level (normal OTDR measurement mode), or Continue to continue averaging a measurement that you have stopped.
The Settings screen 1 Getting Started Averaging Time • Avg. Time: Averaging time of a measurement. The measurement is stopped automatically when this time has elapsed. Larger Averaging Times increase the dynamic range by reducing the noise floor of the OTDR. The specified dynamic range is reached after 3 minutes. NOTE This parameter can also be configured to be Number of Averages: a specified number of measurement acquisitions. Number of Averages is a power of 2.
1 Getting Started The Settings screen N O TE The way in which the Reflectance and Front Connector Thresholds are calculated depends on how you have configured the Reflectance Parameter in the Instrument Config OTDR Settings screen (see “How to Set the OTDR Settings” on page 134). A Reflection Height Threshold value of 0.0 dB, or a Front Connector Threshold value of -.- dB means that the Threshold is not checked. Non-Reflectance Threshold End Threshold • NonRefl Thres: the Non-Reflectance Threshold.
The Settings screen 1 Getting Started Figure 13 The Pass/Fail Parameters Settings page You can change the following parameters from this page: Non-Reflectance Limit • NRefl. Limit: Non-Reflectance Limit. All Events with an Insertion Loss greater than this limit are reported in the Pass/Fail test Table. Gainers are never entered in the Pass/Fail test table. This is because it is not possible to accurately measure the true Insertion loss of a gainer without taking a twoway Averaging Measurement.
1 Getting Started The Settings screen active, you see a value of -.- dB in the Refl. Limit edit field. Connector Loss Limit • Conn. Loss Limit: Insertion Loss for the Connector. A Pass/Fail test checks whether any Reflective Events have an Insertion Loss greater than this limit. For all Events which exceed the limit, you see an entry in the Pass/Fail Test table. So, if the Connector Loss limit is 0.8dB, all Events with an Insertion Loss greater than 0.8dB are entered in the Pass/Fail Test table.
The Settings screen 1 Getting Started Total Link Loss • Total Link Loss: Loss over whole fiber. This is calculated as the loss between the Horizontal Offset (see “How to Set the Horizontal Offset” on page 96) and the Fiber End. An End Event must be present before this test can be performed. See “How to Set the Fiber End” on page 98. If the Loss between the Horizontal Offset and the Fiber End is greater than this limit, this is reported in the Pass/Fail test table.
1 Getting Started The Settings screen not appear in the Event Table, they are reported in the Pass/Fail test table. If you select New Events, you should also set at least one other parameter in the Pass/Fail Param. window. This feature is best used with a locked Event Table. See “How to Lock the Event Table” on page 91. The check for New Events uses the current Scan Trace thresholds. Link Length • Link Length: Distance to Fiber End.
The File Utilities screen 1 Getting Started limit is not active, you see a value of -.--- km in the Link Tolerance edit field. If no Length Tolerance is set, the distance between the Horizontal Offset and the Fiber End must be exactly the same as the Link Length. If no Link Length has been set, the value of the Length Tolerance is irrelevant. Event Masking • Event Masking: Specify events to be masked. See “How to Mask Events” on page 92.
1 Getting Started The File Utilities screen Figure 14 Search for files The File Utilities screen You can use the UP and DOWN cursors to look at files on the current device (by default, this is the Mini-OTDR’s internal directory structure). At the bottom of the screen, you see information about the currently highlighted file. Press SELECT to select the highlighted file or directory. When a file is selected, you see a tick next to it. You may select as many files as you like.
The File Utilities screen 1 Getting Started Copy: Copy the currently selected file(s). When you select this option, you may choose a new directory or a different device. If no file is selected, this option is grayed. Print: Print the currently selected file(s). You must have a printer connected to the Mini-OTDR. For more information, see “How to Print the Measurement” on page 100. If no file is selected, this option is grayed. NOTE You may only print traces. Traces usually have the extension .SOR, .
1 Getting Started EasyMode If you try to format the internal device, your configuration is lost and your Mini-OTDR must be reconfigured. Delete directory RmDir: Delete a directory. After you have selected RmDir move to the directory you want to delete, changing device if necessary. Then cursor RIGHT to Delete and press SELECT. N O TE You cannot delete a directory if there are any files in that directory. Create directory MkDir: Create a new directory.
EasyMode 1 Getting Started Figure 15 EasyMode popup panel EasyMode popup panel The following functions are available on the EasyMode popup panel: • [CANCEL] - exit the popup panel. • [SAVE] - save the current file. [SAVE] is equivalent to [FILE] in OTDR mode. See “How to Save the Measurement” on page 104 • [PRINT]- print the current trace. [PRINT] is equivalent to [FILE] in OTDR mode. See “How to Print the Measurement” on page 100.
1 Getting Started Getting Help Settings file A settings file (“.SET”) just contains values from the Settings menu. See the note on page 50. • [OFFSET] - change the offset. Use the cursors to move the vertical position of the trace on the screen. [OFFSET] is equivalent to [VIEW] in OTDR Mode. • [CLOSE] - return to Applications Screen, as in the OTDR Mode popup panel option. • [EVENTS] - show or hide the Event Table. Equivalent to [VIEW] in OTDR mode.

2 2 Additional Features Additional Features introduces additional features of the Agilent Technologies E6000C Mini-OTDR (Optical Time Domain Reflectometer). Here you will find descriptions of how an OTDR works, and how you can add external features to your Mini-OTDR. How the OTDR Works The OTDR repeatedly outputs an optical pulse into the connected fiber and measures the reflections from this pulse.
2 Additional Features Events Events Events are changes in the fiber causing the trace to deviate from a straight line. Events can be Reflective or Non-Reflective. Reflective Events Reflective Events occur when some of the pulse energy is reflected, for example at a connector. Reflective Events produce a spike in the trace (you see a steep rise and fall in the graph: see the first diagram below).
Events 2 Additional Features What You Can Measure with the OTDR The OTDR displays the relative power of the returned signal against distance.
2 Additional Features External connections greater than the End Threshold. See “How to Set the Fiber End” on page 98 for more details. As a result, the event parameters’ loss, reflectance, and distance are calculated and listed. External connections Figure 17 shows the external connections to the MiniOTDR.

C C Specifications Specifications describe the instrument’s warranted performance, measured with typical PC-type connectors. Uncertainties due to the refractive index of fiber are not considered. Specifications vs. The following section contains both Specifications and Characteristics Characteristics: • Specifications describe the instrument’s warranted performances. • Characteristics and typical data provide information about the non-warranted instrument performance.
C Specifications Definition of Terms / Measurement Conditions Definition of Terms / Measurement Conditions Generally, the wavelengths are given by the specific module. Therefore, the measurement conditions do not contain the wavelength. Unless otherwise limited, all specifications are valid for the specified environmental conditions. All data presented in the ± form are to be understood as peak-to-peak variation divided by 2.
Definition of Terms / Measurement Conditions C Specifications Backscatter coefficient The ratio of the optical pulse power (not energy) at the OTDR output to the backscatter power at the near end of the fiber (z = 0). This ratio is inversely proportional to the pulse width, because the optical pulse power is independent of the pulse width. The ratio is expressed in dB. NOTE A typical value is approximately 50 dB for 1 µs pulse width, depending on the wavelength and the type of fiber.
C Specifications Definition of Terms / Measurement Conditions Conditions: Continuous fiber with no discrete losses, for a power range from the beginning of the backscatter signal to the point where the specified →signal-to-noise ratio is reached, at specified instrument settings.
Definition of Terms / Measurement Conditions C Specifications ∆SL = distance scale error ∆LS = distance sampling error L otdr - L Distance sampling error (±∆L S) Distance Offset Error (∆L0) Average slope = distance scale error (∆SL) 0 0 Location L NOTE The distance uncertainty does not include the uncertainty of the →group of the fiber under test, because the OTDR measures transit times and calculates distances by division by the user-defined fiber’s group refractive index.
C Specifications Definition of Terms / Measurement Conditions Measurement: Select Optimize Resolution for best accuracy. Since the precise location of the front panel connector is usually not directly accessible, use a short reference fiber (for example, 100 m, to exclude any influence from distance scale error) with known length L and open end to create a reflective event. Then measure the length of the fiber by determining the location of the reflective event LOTDR as shown in Figure 4.
Definition of Terms / Measurement Conditions C Specifications The influence of the finite sample spacing can be excluded by inserting additional fibers. Their lengths must be chosen so that they don’t coincide with multiples of the distance sample spacing. For each combination, use the total length of fiber to determine the distance offset error. Finally, average all distance offset results.
C Specifications Definition of Terms / Measurement Conditions Measurement: The measurement is similar to the measurement of distance offset error. Divide the calculated distance sampling interval in at least four distance increments and prepare incremental fibers to cover all these increments. For example, to divide a sampling interval of 10 m into 4 intervals, one needs two incremental fibers of 2.5 m and 5 m to generate increments of 2.5 m, 5 m and 7.5 m.
Definition of Terms / Measurement Conditions C Specifications LOTDR = the distance measured with the OTDR, at the given OTDR group index setting T = time of flight between the two locations on the fiber, measured at the wavelength of the OTDR N = OTDR group index setting NOTE Relatively long lengths of fibers, for example, 10 km, are to be used to evaluate the distance scale error, in order to remove the influence from finite distance sampling spacing.
C Specifications Definition of Terms / Measurement Conditions Event deadzone The displayed length of a reflective event from the start to the point where the trace has fallen to 1.5 dB below the peak. Conditions: Reflective, lossless event with specified reflectance, at specified instrument settings. 1.5 dB Event Deadzone Distance Group index (of a fiber) The refractive index of a fiber that corresponds to the velocity of the modulation content (group velocity) of an optical wave in a fiber.
Definition of Terms / Measurement Conditions C Specifications Loss accuracy, backscatter measurements (1 dB steps) The maximum loss error, in dB, for any fiber section with a loss of 1 dB, that is the maximum difference between the displayed loss, Aotdr, and actual loss, A, of the section.
C Specifications Definition of Terms / Measurement Conditions Measurement: Connect a long fiber, for example 50 km, to the OTDR and calculate the 1 dB loss error as follows. Generate two undisturbed backscatter traces with a 1 dB vertical difference. Measure this difference, AOTDR, along the length of the fiber. Also, measure the power difference, A, with a calibrated optical power meter.
Definition of Terms / Measurement Conditions C Specifications Conditions: Correct backscatter coefficient for the fiber under test entered into the OTDR prior to measurement, undisturbed backscatter trace in front of the reflectance under test, for a given reflectance range and a power range from the beginning of the backscatter signal to the point where the specified →signal-to-noise ratio is reached, at specified instrument settings Noise level (98%) The displayed power level such that 98% of the noise
C Specifications Definition of Terms / Measurement Conditions Output power stability (CW) Peak-to-peak variation of the output power in CW mode. Conditions: Jumper fiber attached to the OTDR port; output power stability measured with an optical power meter at the end of the jumper fiber. Warmup-time and observation period as specified. Power meter averaging time 100 ms.
Definition of Terms / Measurement Conditions C Specifications Definition of Terms - Power Meter Submodule Noise: One half of the peak-to-peak change of displayed power level with constant input power level. Conditions: Observation time as specified (drift effects excluded). Power range: The power range is defined from the highest input power level to the smallest input power level that causes a noticeable change of displayed power level. Conditions: Wavelength and Averaging Time as specified.
C Specifications Characteristics Definition of Terms - Visual Fault Finder Submodule Output Power Level (CW) The output power at the specified wavelength, measured at the end of a jumper cable. The wavelength representing the center of mass of selected peaks.

E E Cleaning Information The following Cleaning Instructions contain some general safety precautions, which must be observed during all phases of cleaning. Consult your specific optical device manuals or guides for full information on safety matters. Please try, whenever possible, to use physically contacting connectors, and dry connections. Clean the connectors, interfaces, and bushings carefully after use.
E Cleaning Information Cleaning Instructions for this Instrument For more information, please consult the Agilent Technologies Pocket Guide Cleaning Procedure fir Lightwave Test and Measurement Equipment (Agilent Part Number 5963-3538F) 272 E6000C Mini-OTDR User’s Guide, E0302
Safety Precautions E Cleaning Information Safety Precautions Please follow the following safety rules: • Do not remove instrument covers when operating. • Ensure that the instrument is switched off throughout the cleaning procedures. • Use of controls or adjustments or performance of procedures other than those specified may result in hazardous radiation exposure. • Make sure that you disable all sources when you are cleaning any optical interfaces.
E Cleaning Information Why is it important to clean optical devices ? Why is it important to clean optical devices ? In transmission links optical fiber cores are about 9 µm (0.00035") in diameter. Dust and other particles, however, can range from tenths to hundredths of microns in diameter. Their comparative size means that they can cover a part of the end of a fiber core, and as a result will reduce the performance of your system.
Standard Cleaning Equipment E Cleaning Information Standard Cleaning Equipment Before you can start your cleaning procedure you need the following standard equipment: • Dust and shutter caps • Isopropyl alcohol • Cotton swabs • Soft tissues • Pipe cleaner • Compressed air Dust and shutter caps All of Agilent Technologies’ lightwave instruments are delivered with either laser shutter caps or dust caps on the lightwave adapter.
E Cleaning Information Standard Cleaning Equipment Using isopropyl alcohol If you use isopropyl alcohol to clean your optical device, do not immediately dry the surface with compressed air (except when you are cleaning very sensitive optical devices). This is because the dust and the dirt is solved and will leave behind filmy deposits after the alcohol is evaporated.
Standard Cleaning Equipment E Cleaning Information Reuse of swabs Swabs should be used straight out of the packet, and never used twice. This is because dust and dirt in the atmosphere, or from a first cleaning, may collect on your swab and scratch the surface of your optical device. Soft tissues These are available from most stores and distributors of medical and hygiene products such as supermarkets or chemists’ shops.
E Cleaning Information Use of pipe cleaners Standard Cleaning Equipment The best way to use a pipe cleaner is to push it in and out of the device opening (for example, when cleaning an interface). While you are cleaning, you should slowly rotate the pipe cleaner. Only use pipe cleaners on connector interfaces or on feed through adapters. Do not use them on optical head adapters, as the center of a pipe cleaner is hard metal and can damage the bottom of the adapter.
Additional Cleaning Equipment E Cleaning Information Additional Cleaning Equipment Some Cleaning Procedures need the following equipment, which is not required to clean each instrument: • Microscope with a magnification range about 50X up to 300X • Ultrasonic bath • Warm water and liquid soap • Premoistened cleaning wipes • Polymer film • Infrared Sensor Card Microscope with a magnification range about 50X up to 300X A microscope can be found in most photography stores, or can be obtained through or spec
E Cleaning Information Additional Cleaning Equipment Ultrasonic bath Ultrasonic baths are also available from photography or laboratory suppliers or specialist mail order companies. An ultrasonic bath will gently remove fat and other stubborn dirt from your optical devices. This helps increase the life span of the optical devices. Use of solvents Only use isopropyl alcohol in your ultrasonic bath, as other solvents may damage.
Preserving Connectors E Cleaning Information Polymer film Polymer film is available from laboratory suppliers or specialist mail order companies. Using polymer film is a gentle method of cleaning extremely sensitive devices, such as reference reflectors and mirrors. Infrared Sensor Card Infrared sensor cards are available from laboratory suppliers or specialist mail order companies. With this card you are able to control the shape of laser light emitted.
E Cleaning Information Dust Caps and Shutter Caps When inserting the ferrule of a patchcord into a connector or an adapter, make sure that the fiber end does not touch the outside of the mating connector or adapter. Otherwise you will rub the fiber end against an unsuitable surface, producing scratches and dirt deposits on the surface of your fiber. Dust Caps and Shutter Caps Be careful when replacing dust caps after use.
Immersion Oil and Other Index Matching Compounds E Cleaning Information Immersion Oil and Other Index Matching Compounds Where it is possible, do not use immersion oil or other index matching compounds with your device. They are liable to impair and dirty the surface of the device. In addition, the characteristics of your device can be changed and your measurement results affected. Cleaning Instrument Housings Use a dry and very soft cotton tissue to clean the instrument housing and the keypad.
E Cleaning Information How to clean connectors • Use compressed air to blow away any remaining filament left by the swab. Heavy dirt If the above procedure is not enough to clean your instrument, follow one of the procedures below. Please consult “Cleaning Instructions for this Instrument” on page 271 for the procedure relevant for this instrument.
How to clean connectors Infrared sensor card E Cleaning Information To assess the projection of the emitted light beam you can use an infrared sensor card. Hold the card approximately 5 cm from the output of the connector. The invisible emitted light is project onto the card and becomes visible as a small circular spot. Preferred Procedure Use the following procedure on most occasions. 1 Clean the connector by rubbing a new, dry cotton-swab over the surface using a small circular movement.
E Cleaning Information How to clean connector adapters 3 Blow away any remaining lint with compressed air. How to clean connector adapters C A UT IO N Some adapters have an anti-reflection coating on the back to reduce back reflection. This coating is extremely sensitive to solvents and mechanical abrasion. Extra care is needed when cleaning these adapters. Preferred Procedure Use the following procedure on most occasions.
How to clean connector interfaces E Cleaning Information How to clean connector interfaces C A U TI O N Be careful when using pipe-cleaners, as the core and the bristles of the pipe-cleaner are hard and can damage the interface. Do not use pipe-cleaners on optical head adapters, as the hard core of normal pipe cleaners can damage the bottom of an adapter. Preferred Procedure Use the following procedure on most occasions.
E Cleaning Information How to clean bare fiber adapters 5 Using a new, dry pipe-cleaner, and a new, dry cottonswab remove the alcohol, any dissolved sediment and dust. 6 Blow away any remaining lint with compressed air. How to clean bare fiber adapters Bare fiber adapters are difficult to clean. Protect from dust unless they are in use. C A UT IO N Never use any kind of solvent when cleaning a bare fiber adapter as solvents can damage the foam inside some adapters.
How to clean lenses C A U TI O N E Cleaning Information Be careful when using pipe-cleaners, as the core and the bristles of the pipe-cleaner are hard and can damage the adapter. 2 Clean the adapter by rubbing a new, dry cotton-swab over the surface using a small circular movement. 3 Blow away any remaining lint with compressed air. How to clean lenses Some lenses have special coatings that are sensitive to solvents, grease, liquid and mechanical abrasion.
E Cleaning Information How to clean instruments with a fixed connector interface 2 Clean the lens by rubbing the cotton-swab over the surface using a small circular movement. 3 Using a new, dry cotton-swab remove the alcohol, any dissolved sediment and dust. 4 Blow away any remaining lint with compressed air. How to clean instruments with a fixed connector interface You should only clean instruments with a fixed connector interface when it is absolutely necessary.
How to clean instruments with an optical glass plate E Cleaning Information Never try to open the instrument and clean the optical block by yourself, because it is easy to scratch optical components, and cause them to be misaligned. How to clean instruments with an optical glass plate Some instruments, for example, the optical heads from Agilent Technologies have an optical glass plate to protect the sensor. Clean this glass plate in the same way as optical lenses (see “How to clean lenses” on page 289).
E Cleaning Information Infrared sensor card How to clean instruments with a physical contact interface To assess the projection of the emitted light beam you can use an infrared sensor card. Hold the card approximately 5 cm from the interface. The invisible emitted light is project onto the card and becomes visible as a small circular spot. Preferred Procedure Use the following procedure on most occasions.
How to clean instruments with a recessed lens interface E Cleaning Information How to clean instruments with a recessed lens interface W A R N IN G For instruments with a deeply recessed lens interface (for example the Agilent Technologies 81633A and 81634A Power Sensors) do NOT follow this procedure. Alcohol and compressed air could damage your lens even further. Keep your dust and shutter caps on, when your instrument is not in use. This should prevent it from getting too dirty.
E Cleaning Information How to clean optical devices sensitive to mechanical stress 2 Clean the interface by rubbing the cotton-swab over the surface using a small circular movement. 3 Take a new, dry soft-tissue and remove the alcohol, dissolved sediment and dust, by rubbing gently over the surface using a small circular movement. 4 Blow away any remaining lint with compressed air.
How to clean metal filters or attenuator gratings E Cleaning Information Alternative Procedure For these types of optical devices you can often use an ultrasonic bath with isopropyl alcohol. Only use the ultrasonic bath if you are sure that it won’t cause any damage anything to the device. 1 Put the device into the bath for at least three minutes. 2 Blow away any remaining liquid with compressed air. If there are any streaks or drying stains on the surface, repeat the cleaning procedure.
E Cleaning Information Additional Cleaning Information Use this procedure particularly when there is greasy dirt on the device: 1 Put the optical device into a bath of isopropyl alcohol, and wait at least 10 minutes. 2 Remove the fluid using compressed air at some distance and with low pressure. If there are any streaks or drying stains on the surface, repeat the whole cleaning procedure.
Additional Cleaning Information E Cleaning Information How to clean large area lenses and mirrors Some mirrors, as those from a monochromator, are very soft and sensitive. Therefore, never touch them and do not use cleaning tools such as compressed air or polymer film. Coated lenses Some lenses have special coatings that are sensitive to solvents, grease, liquid and mechanical abrasion. Take extra care when cleaning lenses with these coatings.
E Cleaning Information Additional Cleaning Information 2 Put a little liquid soap on the surface and gently spread the liquid over the whole area. 3 Wash off the emulsion with water, being careful to remove it all, as any remaining streaks can impair measurement accuracy. 4 Take a new, dry soft-tissue and remove the water, by rubbing gently over the surface using a small circular movement. 5 Blow away remaining lint with compressed air.
