Leica M Series User Manual Quick Start Guide 68
If you wear glasses:
1. Hold the eyepiece firmly and rotate the
eyecups clockwise towards the rear, as
otherwise the viewing distance is too great.
2. If an eyepiece is equipped with the inte-
grated dioptric correction, turn the value to
the "0" mark.
By the way, one benefit of viewing with
eyeglasses is a drastically lower risk of bacte-
rial transmission (see page 77). The soft mate-
rial of the eyecup also ensures that your glasses
will not be scratched, even if they contact the
eyepiece.
Using the Eyepieces
If you do not wear glasses:
1. Hold the eyepiece firmly and rotate the
eyecups forwards counterclockwise.
2. If an eyepiece is equipped with the inte-
grated dioptric correction, turn the value to
the "0" mark.
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.
Each eyepiece offers a certain magnification
factor that has a determinative effect on the
total magnification. Furthermore, all Leica
eyepieces can be equipped with practical grati-
cules that enable measuring and quantifying of
specimens.
Dioptric correction
A built-in dioptric correction is available for
eyeglass wearers. For more information, refer
to page 78.
