the stereo microscope.
Coarse focusing knobs (1a, 1b):
Pre-focusing, large distance between
specimen and objective.
Fine focusing knobs (2a, 2b):
The ne focus is used for image sharp-
ness. Fine and precise regulation of the
distance between the specimen and the
objective.

the correlation between the di-
rection of rotation of the focusing
knobs and the vertical movement
of the zoom unit.

Zooming knobs
Turn the zooming knobs (1a, 1b) on the
right and left of the zooming body (2) to

Turning the knob forward
 Magnication decrease
Turning the knob backward
 Magnication increase
The magnication values are marked on
the right-hand zooming knob (1b).
