Spectrogoniometry and quartz birefringence study set

We have specifically developed a kit for analyzing the birefringence of a quartz blade associated to a Paton dispersive grating. By placing this set between two polarizing strips, you can then analyze the grooves produced by the interferences between the ordinary and extraordinary waves coming from the quartz blade.

- Support: 1 Paton format grating support mechanical stage
- Components:
. 2 rotary polarizing eye cups 360° for ref. 202 624
. 1 Paton 100 lines/mm dispersive grating
. 1 birefringent quartz blade:
* Crystal axis parallel to the sides
* 10 x 10 mm opening, 1 mm thickness
* Paton format
