1. Safety notes

• For power supply use only electrical sockets

with ground contact.

2. Description, technical data

The monocular microscope allows two-

dimensional viewing of objects (thin sections of

plant or animal specimen) in 40x to 1500x mag-

nification. It is fitted with polarisation equipment.

Stand: Robust, all metal stand with arm perma-

nently connected to the base. Focussing by

means of separate knobs for coarse and fine

adjustment located on either side of the stand

and operated by rack and pinion drive with ball

bearings and retaining lever, adjustable stopper

for protecting the object slides and objective.

Focus range: 15mm, resolution of fine focussing

adjustment: 0.002 mm

Tube: Monocular inclined 30°, head rotation

360°

Polarisation equipment: Polariser and ana-

lyser

Eyepiece: Wide field eyepieces WF 10x 18 mm

and 15x 13 mm

Objectives: Inverted objective revolver with 4

plan achromatic objectives 4x / 0.10, 10x / 0.25,

40x / 0.65, 100x / 1.25 (oil)

Magnification: 40x – 1500x

Object stage: x-y cross table, 155 x 145 mm

with object guide and coaxial adjustment knobs

perpendicular to the object stage, adjustment

range 50 x 76 mm

Illumination: Adjustable LED lighting integrated in

base, universal 85 to 265 V, 50/60 Hz power supply

(oil) objective is chosen, objective oil must be dripped onto the slide. To determine the magnification at which you are viewing a specimen, multiply the power of the eyepiece by the power of the objective. • Adjust the holding brake to give a suitable degree of tightness in the focusing mechanism. • Adjust the coarse-focusing-knob which moves the stage up until the specimen is focused. Be careful that the objective does not make contact with the slide at any time.

4.3 Changing the fuse • Turn off the power switch and unplug the mains plug. • Unscrew the fuse holder on the back of the stand base with a screwdriver. • Replace the fuse and reinsert the holder in its socket. 5. Storage, cleaning and disposal • • • • • • • • • • Keep the microscope in a clean, dry and dust free place. When not in use always cover the microscope with the dust cover. Do not expose it to temperatures below 0°C and above 40°C and a max. relative humidity of over 85%.
