Dioptric correction

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.
