Leitz ICR Polarizer Insert 573 097 for Ergoplan
$480.00
This is a polarizer slider for the Leitz (Leica) Ergoplan semiconductor microscope � it may fit other instruments as well. The Leitz part number is 573 097. The dimensions of the slider are 120mm in length, 28.5mm wide, and 11.5mm deep. There is a small bevel on the upper forward edge of the slide to prevent accidental insertion of the slide in the inverted position.
The slider consists of three elements. The first is the actual polarizing filter. Then there is a plate inserted in a cutout that appears to be a quarter-wave plate that is oriented so the permitted vibration directions are parallel to the analyzer and polarizer � in other words, no light is passed in that position. Then there is a third element opposite the polarizer. Behavior of the slider was similar whether it was upright or inverted � when an analyzer was placed in front of the slider and brought to the extinction position (no light transmission) and the slide was inverted, there continued to be zero transmission. The central plate also has a pair of set screws so it can be critically set.
I have been unable to figure out the function of these additional two plates. There was an earlier version of the Leitz reflected light interference contrast in which the polarizer could be rotated behind a fixed quarter-wave plate � this permitted a variation in the contrast without having to move the Wollaston prisms with respect to the optic axis, instead the polarizer is rotated behind the fixed quarter-wave plate. However, in the Ergoplan, the polarizer is fixed and the Wollastons are adjustable.
The slider is in near-perfect cosmetic condition, and the optical elements are in perfect condition.
