Attaching the Polarizer for the Diascopic Illumination
There are two types of polarizers for the diascopic illumination. One is the C-SP polarizer for the
diascopic illumination equipped with a polarizer only. And another is the D-DP rotatable polarizer
for the diascopic illumination equipped with a polarizer and a 1/4 lambda plate. The C-SP polarizer
is used for the polarization microscopy under the diascopic illumination. The D-DP rotatable
polarizer is used for the polarization DIC microscopy under the diascopic illumination. Select the
polarizer suitable for the microscopy.
1 Check the orientation indicator for the C-SP
polarizer. Or check the index for the D-DP
rotatable polarizer.
2 Place the polarizer onto the field lens on the base
of the microscope. The orientation indicator or the
index must face the front of the microscope.
3 Tighten the setscrew to fix the polarizer. The
orientation of the polarizer must be adjusted for
each observation.

Adjusting the orientation of the polarizer
After attaching the polarizer for the diascopic illumination, adjust the orientation of the
polarizer to a right angle to the orientation of the analyzer. For the procedure of adjusting
the orientation, see “15. Polarizer for the Diascopic Illumination” in “III. Operation of
Each Part.”
