Most of our technicians have been with the company for over 20 years, and some have been with us right from our beginnings in 1975 when the company was founded.

25 years ago we made 300mm fused silica membranes, 25 microns thick (0.001”) optically polished both sides. We have advanced since then. Now parts can be fabricated in size ranges from as large as 609mm (24”), as thin as 25 micron thick and as small as .203mm. Our customers are among the top technology companies in the world including Applied Materials, Intel, KLA Tencor, Philips Medical, Boeing, NASA, Raytheon and others.
