2. Description, technical data
The monocular microscope allows two-dimensional
viewing of objects (thin sections of plant or animal
specimen) in 40x to 1000x magnification.
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 retain-
ing lever, adjustable stopper for protecting the
