Surface of revolution
Fine grind inspection
After polish Inspection
We use the following substrates:
All of our substrates are free from edge chips
or "clam shells".
After diamond generation, fine grinding,
polishing, and figuring, each
optic undergoes several hours of testing and
figure touch up, as long as needed to achieve a
We preform, not one, but several different
optical tests during fabrication.
The results from each test are then cross-
checked against each other in order to provide
an accurate representation of the optical
Our testing methods include.
*Foucault-Null Test (we do not offer Foucault
data reduction reports).
*Figure of Revolution Test
Our data is composed of several hundred points
of data reference. The numbers are not usually
going to match Foucault data reduction, it's just
the way it is. I offer the interferometric data
page as a courtesy, this is done after all other
testing has been completed.
