1. Safety notes

• For power supply use only electrical sockets

with ground contact.

Caution! The Stirling engine becomes hot during

use. Risk of burns!

• Do not touch the lamp during or immediately

after use.

2. Description, technical data

The laboratory microscope BS-200 allows two-

dimensional viewing of objects (thin sections of

plant or animal specimen) in 40x to 1000x mag-

nification.

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

Tube: Binocular at 30° angle, rotatable through

360°, viewing distance adjustable between 50

and 76 mm, ±5 dioptric compensation for both

eyepieces

Eyepiece: Pair of eyepieces PL10x 18 mm with

infinite optics and “high eye point”

Objectives: Inverted objective revolver with

plan achromatic infinite objectives 4x, 10x, 40xS

und 100xS Oil

Magnification: 40x, 100x, 400x, 1000x

Object stage: x-y cross table, 150 x 140 mm

with object guide and coaxial adjustment knobs

perpendicular to the object stage, adjustment

range 50 x 76 mm

Illumination: Adjustable 6 V, 20 W halogen

lamp, built-in transformer for 90 to 240 V mains

voltage

Condenser: Condenser NA1.25, iris diaphragm,

focussed via rack and pinion drive

Dimensions: 320 x 200 x 400 mm³ approx.

Weight: 6.7 kg approx.

(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.

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%. Always unplug the mains plug before cleaning or maintenance. Do not clean the unit with volatile solvents or abrasive cleaners. Do not disassemble objective or eyepieces to attempt to clean them.
