Polarizer for the Diascopic Illumination

Polarizer for the diascopic illumination
The following two types of polarizers for the diascopic illumination can be used for the product.
Polarizer
C-SP polarizer for the
diascopic illumination
D-DP rotatable
polarizer for the
diascopic illumination
• C-SP polarizer for the diascopic illumination
The simplified polarization microscopy under the diascopic illumination can be performed with the C-
SP polarizer for the diascopic illumination and the analyzer slider. The sensitive color polarization
microscopy under the diascopic illumination can be performed with the C-SP polarizer for the
diascopic illumination, the analyzer slider, and the lambda plate slider for the diascopic illumination.
• D-DP rotatable polarizer for the diascopic illumination
When the D-DP rotatable polarizer for the diascopic illumination is attached, the DIC microscopy under
the diascopic illumination can be performed with the universal condenser, the analyzer slider, the
condenser DIC prism, the objective DIC prism and the lambda plate slider for the diascopic illumination.
The contrast of the DIC contrast image can be adjusted with the polarizer orientation.
Attaching the C-SP polarizer for the diascopic
illumination and adjusting the orientaion
Place the polarizer over the field lens at the microscope
base with the polarizer orientation mark facing the front.
The orientation of the polarizer can be changed by
turning the whole polarizer. Perform the following to
make a crossed Nicols position with the polarizer and the
analyzer.
1 Place the polarizer and analyzer into the optical
path and fully open the aperture diaphragm.
2 Remove one eyepiece from the eyepiece tube and
look inside the open sleeve. You can see the pupil
of the objective as a bright circle and can see black
patterns in the circle.
3 Turn the whole polarizer for the diascopic
illumination in either direction until a dark cross
appears in the viewfield as shown in the figure.
This is the crossed Nicols position.
4 Secure the polarizer for the diascopic illumination
by tightening the setscrew.
