2. Description, technical data
The trinocular microscope allows two observers to
have a two-dimensional view of objects (thin sec-
tions of plant or animal specimen) at a magnifica-
tion of 40 to 1500 times. It also allows a camera to
be attached at the same time for photographic or
video-recording documentation 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
object slides and objective. Focus range: 15mm,
resolution of fine focussing adjustment: 0.002 mm
Tube: Trinocular Seidentopf head, 360° rotatable,
binocular tubus with 30° viewing angle, viewing
distance adjustable between 54 and 75 mm, ±5
dioptric compensation for both eyepieces, one tube
with vertical viewing angle
