The Correct Interpupillary Distance - Leica S Series User Manual

The correct interpupillary distance

The interpupillary distance is correctly
set if you see a single circular image field
when looking at a specimen.
If you are still a novice microscope user, you
may need a short time to become accustomed
to this. Not to worry - after a little while, it will
become automatic.
Reference value
The interpupillary distance can be set between
55 and 75 mm.
An "exit pupil distance" is the distance
between eye and eyepiece. With the
10×/23B wide-field eyepiece for eyeglass
wearers, it is approx. 22 mm. For those who do
not use the eyepiece for eyeglass wearers, it is
12 mm.
Leica S Series
Setting the eye distance
1. Bring the eyes slowly to the eyepieces.
2. Push the tubes together or apart with both
hands until you see a single round, circular
image field without shadows with both
eyes.
