Microscope Operation:
Using the Eye Shields
If the user wears glasses, turn the eye shields down (1) to prevent
the glasses from touching the eyepiece and avoid damaging the
glasses or the eyepieces.
Open the eyesheilds (2) to prevent stray light from disturbing
observation.
Adjust the Field Diaphragm
By limiting the diameter of the beam of light entering the
condenser, the field diaphragm can strengthen image contrast.
When the image of the field diaphragm is on the edge of the field
of view the clearest image is obtained.
Adjust the field diaphragm rod (1) to minimize the field
diaphragm. The image of the field diaphragm can be seen through
the eyetube.
Adjust the right and left centering screws (2) on the field
diaphragm until the image is centered.
Open the field diaphragm slowly. If the image is inscribed in the
field of view, the field diaphragm has been centered properly.
Open the field diaphragm slightly when using the microscope.
Use the Ground Glass Filter
When the ground glass filter slider (1) is pulled to the left it is used
to center the filament. When it is pulled to the right it will help
create uniform illumination. Typically this filter is set to the right in
the engaged position.
Use the Color Filter
The color filter (1) can make the background more suitable and
improve image reflection. There are four types of color filters that
are typically used: blue, green, yellow and white.
