SCHOTT SUPREMAX 33® Gains Traction in Telescope Glass Market

January 25, 2011 (SPIE Photonics West in San Francisco Booth #1601) – SCHOTT North America, Inc. today announced that SUPREMAX® 33 rolled borosilicate glass is becoming the material of choice for glass for telescope applications. SUPREMAX 33 glass is made by utilizing SCHOTT’s unique rolling technology - the ideal process to produce thicker sheets for telescope mirrors and lenses.

SUPREMAX 33 from SCHOTT replaces PYREX from Corning, which is no longer available on the market. Some customers have seen an even better quality and clarity from SUPREMAX than from PYREX. “As a mirror manufacturer for both professional and amateur telescope mirrors, SCHOTT is a valuable partner,” said Vaughn Parsons, Owner of Intermountain Optics of Salt Lake City, Utah. “The high quality and easy-to-customize SUPREMAX 33 has definitely improved our mirrors.”

SUPREMAX 33 shares identical properties of SCHOTT’s floated borosilicate glass BOROFLOAT® 33. SUPREMAX 33 offers the qualities of low thermal expansion, high thermal resistance, excellent light transmission and impressive chemical durability and is available in a new, wider range of thicknesses (up to 66.7 mm), extending its application to telescopes. With a low density that makes it 12 percent lighter than soda lime glass, SUPREMAX is a highly versatile material suitable for an unlimited array of applications.

“SCHOTT is proud to have developed a new manufacturing process to create borosilicate glass in sizes that cannot be matched within the industry,” said Karen Elder, marketing manager at SCHOTT North America, Inc. “SCHOTT now offers a high quality and durable borosilicate glass solution that meets an even wider range of industry needs.”
