Dioptric Correction and Parfocality, Adjusting | Leica M165 C B

Dioptric Correction and Parfocality

Leica stereomicroscopes are parfocally matched. The prerequisite for this is the correct setting of the diopters and the parfocality. The following adjustments have to be carried out only once by each user.

Preparations

★★ Move the lever of the video/phototube to the "observation" position and open the diaphragm.

Adjusting

1.Set the dioptric correction for both eyepieces to "0".

2.Select the lowest magnification and focus on a flat specimen.

3.Select the highest magnification and read- just the sharpness.

4.Select the lowest magnification again, but do not look into the eyepieces.

6.Rotate the eyepieces counterclockwise in the "+" direction as far as they will go (+5 diopter settings).

7.Look into the eyepieces.

8.Slowly rotate each eyepiece individually in the "–" direction until each eye sees the object sharply imaged.

9.Select the highest magnification and refo- cus if necessary.

Now, if you adjust the magnification from the lowest to the highest level, the specimen is always brought into sharp focus. If not, repeat the process.
