For photography using artificial light color reversal film for 3200 K, the conversion filter  CB 3 (467852)
produces the correct color temperature in the light path.

The scale on the coarse drive (0 to 400) permits the orienting measurement of the object thickness:

1 increment corresponds to approx. 5 µm
