1. Safety notes

• For power supply use only electrical sockets

with ground contact.

2. Description, technical data

The binocular 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: Binocular Siedentopf head, 30° viewing

angle, 360° rotatable head, viewing distance

adjustable between 54 and 75 mm, ±5 dioptric

compensation for both eyepieces

Polarisation equipment: Polariser and ana-

lyser

Eyepiece: Pair of wide field eyepieces WF 10x

18 mm and WF 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

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. When 100x (oil) objective is chosen, objective oil must be dripped onto the slide.

can be tested by rotating the polariser or the specimen itself. A birefringent object, when rotated continuously, shows up brightly after each 90° rotation and is dark between these positions. In contrast, objects that are isotropic and not birefringent remain dark in all positions. 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.
