• Set optimum polarization image by turning the specimen (turn the specimen itself when the fixed
mechanical stage is used, or the stage when using the rotary mechanical stage!).
• If required, the compensator DIC lambda or Pol lambda sub, ± 10° (3-22/5) can also be inserted in the
reflector slider HD DIC from the right, and the adjusting lever of the latter can be used to optimize the
image contrast.
3.4.8.2
Transmitted-light polarization contrast with reflector slider HD DIC on the
Axiotech
vario
100
The rotary polarizer D ( 3-24/9) is used with the
Axiotech
vario
100.
• Perform steps described in sections 2.13.3,
2.13.4 and 3.3.
• Use screw ( 3-24/8) and bolt ( 3-24/7) to screw
polarizer D in the marked, threaded holes of
the transmitted-light equipment. Use the
supplied pin spanner to tighten the screw.
• Place specimen to be examined on the
microscope stage and fix it.
• Push reflector slider HD DIC ( 3-24/3) into the
reflected-light illuminator until the DIC position
is active ( DIC mark visible on the reflector
slider). The analyzer is integrated in the reflector
slider and is switched in orientation position.
• Unlike DIC, the brightfield position ( H mark
visible on the reflector slider) requires the rotary
analyzer slider ( 3-24/4) to be inserted in the
reflector slider HD DIC until stop on the left
side. The adjusting lever ( 3-24/5) of the
± 10°rotary analyzer slider permits the image
contrast to be further optimized with crossed
polars.
• Use the lower lever (3-23/15) to swing polarizer
D (3-23/13) into the beam path and move the
upper lever (3-23/14) into the zero stop position
(the upper lever will then point to the front).
☞
No filter should be inserted in the beam path for intensity reasons (remove filter slider (3-24/2)).
• Set maximum darkness position in the field of view (crossed polars) by slightly turning the upper lever
(3-24/6) of polarizer D.
