10. Use of the microscope in brightfield
(transmitted light)
10.1 Turning on the microscope
Move the main switch (1) in the “I” (ON) position. (Fig. 20)
10.2 Adjusting the light intensity
Turn the brightness adjustment knob (2) placed on the left side of
the microscope to increase and decrease the brightness. (Fig. 21)
10.3 Adjusting the coarse focus tension
The coarse focusing knob (4) is pre adjusted to a tight tension upon
leaving the factory.
If the nosepiece drops down by itself, or the specimen defocuses
while adjusting the fine focus knob (5), the coarse focus knob is too
loose. Turning the tension adjustment collar (4) in clockwise direction
tightens the coarse focus tension (3). Rotate in the opposite direction
to decrease the tension. (Fig. 22)
10.4 Diopter adjustment
1
Look into the right eyepiece with your right eye only, and focus on
the specimen.
Look into the left eyepiece with your left eye only. If the image is not
sharp, use the diopter adjustment ring (6) to compensate. (Fig. 23)
The adjustment range is ±5 diopter. The number indicated on the
adjustment ring graduation should correspond to the operator’s
diopter correction.
