Leica M125 B, M165 C B Using the Eyepieces, Dioptric Correction, If you do not wear glasses

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.

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

Abuilt-in dioptric correction is available for eyeglass wearers. For more information, refer to page 42

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.

If you wear glasses:

1.Hold the eyepiece firmly and rotate the eyecups counterclockwise 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 bacterial transmission (see page 41). The soft material of the eyecup also ensures that your glasses will not be scratched, even if they contact the eyepiece.
