First test 2005 10 20 Fizeau interferometer



This very simple and crude setup were made.

Object to test  to left. (interference from front- and back side of the  borofloat glass.
Lens creating collimated light
Bemsplitter
650nm laser

The image of the interference pattern were taken by a camera  placed close to the beamsplitter.

This  shot was taken by a digital Canon EOS 20d directly from the setup above. Some parasitic reflections from other lens surfaces is shown in the center. This will be eliminated later.
