Description
This is a special analyzer slider for differential interference contrast work. It fits the Leitz (Leica) Ergoplan microscope and possibly others. The slider dimensions are 120mm in length, 28.5mm wide, and 6.5mm thick. Leitz part number is 573 098.

What makes this particular slider interesting is that it includes, in addition to the analyzer polarizing foil, a properly oriented first-order red (or full lambda) compensator plate. When the slider is inserted so the 'ICR' nomenclature is facing upwards, the first order red plate sits on top of the analyzer and is effectively out of the system - the contrast is then usually apparent as various shades of gray.

Reversing the slider (nomenclature with the lambda symbol facing upwards) places the first order red plate underneath the analyzer foil, effectively between the polarizer and the analyzer. In that position it imparts a shift in the interference produced by the sample into the 'sensitive tint' region of the interference color series. In this position very small shifts in wavelength differential produce dramatic color shifts - from bright yellow to red to deep blue.
