3. Operation of Each Part.

The analyzer can be rotated by first loosening the

analyzer clamp screw [T] and then turning the rotation

dial [2]. The angle of rotation can be read to 0.1

degrees over a range of 0-360 degrees with the

vernier.

The analyzer can be moved out of the optical path by

pushing in the analyzer slider [3]. Although the

analyzer is designed, as a standard, to be inserted

from the right relative to the intermediate tube, it can

also be inserted from the left. In this case, it may be

somewhat difficult to read the angle of rotation since

the readings on the scale, etc. are backward.

Since the intermediate tube contains a built-in depolarizer, it is not necessary to be

concerned about the relationship between the orientation of the polarizing plate and

photomicrographic devices.

When changing the objectives, turn the Bertrand lens

intermediate tube and focus the Bertrand lens.

Centering the Bertrand lens is performed with two

centering screws.

The centering procedure is the same

as that for the condenser except that the condenser

aperture diaphragm image is used instead of the field

diaphragm image.

P-CL 1/4). & tint plate

The P-CL 1/42. & tint plate has a hole in the center. By pushing it into the slot, the sensitive tint

plate (530 nm) is brought into the optical path. Pulling it out brings the 1/47. plate into the optical

path. This plate is used for recognition of very weak birefringence and the determination of X°

and Y" of the specimen.
