We use the following substrates: borosilicate glass, Schott Supremax

33 and Fused quartz. All of our substrates are free edge chips or

"clam Shells".

After diamond generation, fine grinding, polishing, and figuring, each
optic undergoes several hours of testing and figure touch up.

 We use not one, but several optical tests during fabrication.
The results from each test are cross-checked against each other in
order to provide an accurate representation of the optical quality.
Our testing methods include.

*Foucault-Null Test

*Ronchi-Null Test 


*Figure of Revolution Test

*Interferometric Test


Test Data Provided when requested and/or if supplied as contracted.

Test data reports generally contain the following information:


                        Strehl Ratio (primary optics and optical systems)

                        RMS Wave front Error

                        Peak to Valley Wave front Error

                        Wave front Map
