Microscope Operation:
Using the Beam Splitter
Slide the beam splitter (1) to direct light 20% to the eyepieces and
80% to the trinocular port (camera).
Slide the beam splitter the other direction to send light 100% to
the eyepieces.
Adjust the Diopters
Turn the coarse focusing knob and then the fine focus knob to get
a clear image while viewing through the left eyepiece only. Then
look through the right eyepiece. If the image is unclear rotate the
diopter adjustment ring (1).
There is a +/-5 diopter on the ring. The number shown on the
diopter (2) is your eye’s specific setting. Note the number that lines
up with the mark on the side of the eyetube (3). Remember this
number if multiple people are using the microscope.
Focusing
Place the sample on the stage and move the 5x objective into the
light path.
The surface of the sample should be perpendicular to the
objective.
Adjust the right diopter adjustment ring to “0” and look through
the right eyepiece. Adjust the coarse focus knob (1) and then the
fine focus knob (2).
Adjust the Focusing Tension
If it is hard to turn the coarse focus knob or the sample falls out of
focus (the stage drifts), solve the problem by adjusting the focus
tension adjustment ring (1).
To tighten the focus mechanism turn the tension ring clockwise.
To loosen the tension turn it counterclockwise.
Adjust the Interpupillary Distance
When using both eyepieces, hold the base of the prism and rotate
them around the axis until there is only one field of view.
The mark (1) on the side will line up with a number (2) that shows
your specific interpupillary distance. Remember this number if
multiple people are using the microscope.
Interpupillary adjustment range = 50~75mm.
