Interferometry

We have upgraded our interferometer with a new high resolution camera and fringe analysis software. We also put a contrast coating on the test flat which allows us to test both coated and uncoated flats.

Specs are as follows:

Spatial carrier wavefront analysis software for increased accuracy
Traceable certification to 1/20th wave.
Flats up to 5 Inch diameter.
