OOptino  vs Veeco Interferometer

flat - A small area (9mm) of a flat mirror was tested using a high
resolution Veeco interferometer.

- The same area was tested with our standard instrument Optino/Sensoft mounting a cooled CCD camera.

-Both the tests were done at 632.8nm.


Results

Veeco Optino_veecoscale
The wavefront from Veeco (on left) and the wavefront as measured by Sensoft (right).
A clear correspondence between the two is seen.
The P-V measured on the surface is 14nm with rms 2nm
