The AZ Mirror Cells were designed with the input of Carl Zambuto for mirrors under 16 inches in diameter. We are filling a need in the amateur astronomy market for a high quality cell that provides excellent support for the mirror. The Mirror Cells are manufactured in small batches and assembled to order with an average delivery of one week after placement of your order. We use the online program PLOP to determine the position of the support points, and the six point support system is superior over a nine point system for small mirrors.

These cells compliment our custom made mirror cells that target larger mirrors from 16 inches up to 40+ inches.

Attaching the mirror to the mirror cell with Silicon Rubber RTV may seem unconventional, but it's been done for at least 30 years. With the silicone approach, the full weight of the mirror is hanging on the silicone as the scope goes to the horizon, so there is no need for edge support on the mirror. The math shows that deformation from no edge support on small mirrors, less than 15in. diameter is minimal, and well less than RMS surface error of 20 nm, see the article online MIRROR EDGE SUPPORT CALCULATOR by Robert Houdart. Also there is substantial field data to show the performance of small mirrors with the silicone approach is very good, including astrophotography. http://www.cruxis.com/scope/mirroredgecalculator.htm#GluingMirror

It is our understanding that the use of silicone to attach the mirror to a six point floating mirror cell was pioneered by Pete Smitka on his innovative Portaball Telescopes back in the 1990's.

We are working hard to provide the home and commercial telescope builder with the very best products that we can. Thanks for your business, and keep building better scopes!
