Stage rotation
Loosening the stage rotation clamp screw can rotate the
stage. The angle of rotation can be read to 0.1 degrees
from the two vernier scales.
•
45° click-stop
Turning the 45° click-stop lever towards the front until it

&
tint plate.
It can be used to measure retardation up to I A according
to the following procedure.
It is normal to bring the top lens of the condenser into the optical path when observing at a
magnification of
!Ox
or greater. Measuring the retardation or evaluating by interference
color. however. stop down the condenser aperture diaphragm or swing out the top lens even
for a magnification of
!Ox
or higher (with the aperture diaphragm fully opened). and
illuminate with light that is as parallel to the optical axis as possible.
