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.

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 |
