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 binocular polarisation microscope allows

two-dimensional viewing of objects (thin sec-

tions of rock, plant or animal specimen) in 40x to

400x magnification in polarised light.

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 head, 30° viewing angle, 360°

rotatable head, viewing distance adjustable be-

tween 54 and 75 mm, ±5 dioptric compensation

for both eyepieces

Polarisation equipment: Polariser with scale

and analyser, which can be inserted into the tube

Eyepiece: Pair of wide field eyepieces WF 10x

18 mm

Objectives: Inverted objective revolver with 3

achromatic objectives 4x / 0.10, 10x / 0.25, 40x /

0.65

Magnification: 40x, 100x, 400x

Object stage: Circular object stage 120 mm in

diameter, which can be rotated 360°, scale with

Vernier and 2 specimen clips

Illumination: Adjustable 6 V, 20 W halogen

lamp incorporated into the base, universal 85 to

265 V, 50/60 Hz power supply

specimen. There is a definite “click” when each objective is lined up properly. NOTE: It is best to begin with the lowest power objective. This is important to reveal general structural details with the largest field of view first. Than you may increase the magnification as needed to reveal small details. To determine the magnification at which you are viewing a specimen, multiply the power of the eyepiece by the power of the objective.

4.3 Changing the lamp and fuse 4.3.1 Changing the lamp • Turn off the power switch, unplug the mains plug and let the lamp cool down to avoid being burnt. • For safety reasons, remove the eyepiece. • To change the lamp lay the microscope on its back to reach the lid on the bottom side. • Loosen screw C of the lamp socket and push it outwards so that it is in the position shown in Fig.1. • Loosen screw A and open the cover. • To remove the halogen lamp, use a cloth or similar material.
