2. Description, technical data

The monocular microscope with vertical viewing

allows two observers to have a two-dimensional

view of objects (thin sections of plant or animal

specimen) at a magnification of 40 to 1000

times. It also allows a camera to be attached at

the same time for photographic or video-

recording docu-mentation of images.

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: Head with double viewing capability, one

tube with 30° viewing angle, one with vertical

viewing, head rotation 360°

Eyepiece: Pair of wide field eyepieces WF 10x

18 mm

Objectives: Revolver with 4 DIN achromatic

objectives 4x / 0.10, 10x / 0.25, 40x / 0.65, 100x

/ 1.25 oil (with specimen protection)

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