Dioptric compensation

This compensation makes it possible for
people with glasses to adjust the microscope
to their eyes and use the microscope without
glasses. Adjust the diopter compensation ring
of the right eyepiece tube until the image of the
right eyepiece is clear and sharp. Repeat the
procedure for the left eyepiece. (Fig. 7)

Select the desired magnification by rotating the
objective. (Fig. 8)
Total magnification used can be calculated as:
Eyepiece magnification x Zoom magnification
x Objective lens magnification.

Contrast disc

You can use the black/white disc in order to
enhance the contrast of the image when using
the incident illumination.
If you want to look at bright opaque objects,
place the disc with the black side up. (Fig. 9)
