Polarizer Slider (T-P2), Λ Plate (Ti-Dic) - Nikon ECLIPSE MA200 Instructions Manual

3.23.8 Polarizer slider (T-P2), λ plate (TI-DIC)
When performing the simplified polarization microscopy under the diascopic illumination, mount the polarizer
slider on the condenser mount for the supporting pillar for dia-Illuminator 100W.
Push in the slider, and the polarizer enters the optical path.
If you loosen the rotation clamp screw and slightly turn the polarizer, the image contrast changes.
To perform the sensitive color microscopy, pull out the dust-proof plate from the polarizer slider to attach the
TI-DIC λ plate.

1 Focus on the condenser and bring it to the center
by following the instruction in 3.23.2.
2 Select the 50X objective and focus on the sample.
3 Move the stage to remove the sample out of the
view-field. In its place, bring an almost dust-free
area into the view-field. (There must be no dust in
the whole view-field.)
4 Remove an eyepiece from the binocular part to
attach the centering telescope.
(To observe the objective pupil, turn the eyepiece
while pressing the flange on the centering
telescope.)
5 Place the analyzer of the MA200 main body into
the optical path.
6 Push in the slider, and the polarizer enters the
optical path. Confirm that the white index mark on
the polarizer is positioned at the center of the dial
scale. (If it is not, adjust it as described in "4.
Assembly.")
