Leica M series Manual 60

All Leica eyepieces are also available with

built-in dioptric correction, allowing the micro-

scope to be used without glasses even by those

with vision problems. The correction comprises

±5 diopter settings.

Using the Dioptric Correction

1. Set the dioptric correction of both eyepieces

to the mid position ("0" diopter settings.

2. While wearing your glasses, look through

the eyepieces and focus on the specimen.

3. Rotate both eyepieces to the maximum

value of "+5".

4. Hold one eye closed and rotate the other

eyepiece in "-" direction until the specimen

appears sharp.

5. Then, open the other eye and correct the

diopter settings until the image is uniformly

sharp.

Note that when using dioptric correction,

the advantage of parfocality is lost—thus

you have to manually refocus each time you

change the zoom level. To also use parfocality

with dioptric correction, refer to the instruc-

tions on page 61.
