protection.

(Fig. 25)

(continued)

The fine adjustment knob

③

can control the background

interference color change from gray to mauve.

NOTE:

Adjusting the aperture diaphragm at the same

time will provide the best contrast.

Since the differential interference contrast is very
sensitive, there should not be any dirt or dust on the
surface of the sample.

Birefringent materials cannot reach the effect of
differential interference contrast in microscopical
examination.
