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)
