COLOR FILTERS:
The color filter can strengthen image
contrast. Pull the color filter slider (1)
to the left or right and insert the filter
(2) into the slot, then slide the slider
into the light path. There are 4 types
of filter options: blue, green, yellow,
and LBD.
FIELD DIAPHRAGM:
By limiting the diameter of the light
entering the condenser, the field
diaphragm can improve image
contrast. When the image is right
on the edge of the field of view, the
objective lens will obtain the clearest
image. Pull the field diaphragm
adjustment lever (1) out all the way
to minimize the field diaphragm. You
will be able to see it when looking
through the eyepieces. Adjust the
two field diaphragm centering screws
(2) until the image is in the center.
(See example at right). Open the field
diaphragm gradually until the image
is inscribed in the center of the field
of view and the diaphragm is just
outside the edge of the image.
