Using the Eyepieces

 
The eyepieces form the connection
between the tube and the eye of the
observer. Simply push them into the tube and
they are ready to use.
What does "parfocal" mean?
 
"Parfocal" means that a specimen contin-
ues to remain exactly in focus, even if
the magnification on the stereomicroscope
is modified. All stereomicroscopes from Leica
Microsystems are parfocally matched. However,
the parfocality requires a personal dioptric
correction for the user.
Leica S Series
Dioptric correction
In order to parfocally match the stereomi-
croscope, at least one eyepiece with dioptric
correction is necessary. The setup is described
on the following pages:
With two adjustable eyepieces:
from page 35.
If you do not wear glasses:
Depending on the preferences of the observer,
eyecups can be used.
 
To avoid eye infections, we recommend
that every user uses his or her own pair
of eyecups.
User Manual
If you wear glasses:
 
Eyeglass wearers must remove or fold
back the eyecups (Fig. below left), as
otherwise they cannot see the entire field of
