Leica EZ4 HD manual Focusing

Focusing

Focusing raises and lowers the stereomi- croscope using the focusing drive. The specimen is brought into sharp focus as soon as

it is in the focal point of the objective.

The focusing drive can be operated either left- or right-handed.

2.Set the working distance to approx. 100 mm for coarse focusing.

3.Set the magnification changer to the second level (35).

4.Use the focusing drive once again for fine focus.

After you have adjusted the image sharp- ness at high magnification, it remains constant even if you switch magnification levels

(parfocal).
