3.8 Adjusting Iris diaphragm
Swing the iris diaphragm lever (
Fig. 9
) left or right to
adjust the aperture size.
Note:
The iris diaphragm is designed to adjust the
aperture size, not to adjust the brightness although
the brightness will be changed when it's adjusted.
When aperture is adjusted to smaller size, the
contrast will be increased and the depth of field will
be increased as well. Turn up the intensity of the
light if the image is too dim.

) situated between the coarse
focus knob and microscope body on the right side
until the tension is in maintained.
