PRIMARY MIRRORS

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

Have your peace 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.

We are producing Quartz primary mirrors from 10" to 24" at very competitive prices. Quartz substrate is ideal for imaging systems where the focus shift from expansion/contraction of BK-7 or even Pyrex is highly undersirable.

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.

I can be a bit flexible in the focal ratios offered, just let me know what you need and I will work with you.

Lead time varies with production schedules. If we can’t deliver within the time frame quoted, shipping is on us. This offer applies to U.S. retail customers only, other conditions may apply.

Other substrates, sizes and focal ratios are available, please inquire with your specific needs. There maybe times when our work load may require us to turn away orders.
