Dioptric correction with two adjustable eyepieces
If you set the diopters on the adjustable
eyepiece exactly as described, the image
will remain equally sharp and constant (parfo-
cal) from the lowest to the highest magnifica-
tion. 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 stereomicroscopes.
The diopters can be set between +5
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 S6 D and Leica S8 APO, turn the
rotary knob to the "Vis" setting.
2. Turn the dioptric correction on both eyepi-
eces to the center position.
