PRIMARY MIRRORS

All of our primary mirrors come with interferogram(s) and data analysis. Why settle for anything less?.

Have your piece of mind in knowing that what you paid for is exactly what you are getting. Do not settle for a piece of paper provided by others that is intended to be a certificate of quality. As far as we are concerned, the only “certificate of quality” that you should accept is an actual interferogram photo.

Each and every primary mirror is given meticulous attention to detail, from the precise diamond bevels to the pain-staking hand correction to the time-consuming interferometric testing done with double pass auto collimation and Ross-Nulling test setups. All of our interferometers can test coated or un-coated optics. The back surface is ground flat.

Another added bonus that others charge extra for: all of our primary mirrors have enhanced aluminum coatings included in the price, other coatings are available if required.
