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.
