S Series User Manual Quick Start Guide 36
If you set the diopters on the adjustable
eyepiece exactly as described, the
image will remain equally sharp and constant
(parfocal) from the lowest to the highest
magnification. This means you do not have
to refocus when changing magnification. The
focus needs to be readjusted only if you want to
view a specimen detail that is located higher or
lower. Use this advantage as often as possible, it
is not available on all stereo microscopes.
The diopters can be set b5
and -5.
The following adjustments have to be
carried out only once by each user. Using
reticules leads to slightly deviated settings,
which are described in the user manuals on the
reticules (measurement).
Adjusting the diopter settings
1. With Leica S APO, turn the rotary knob to
the "Vis" setting.
2. Turn the dioptric correction on the
adjustable eyepiece to the center position.
