Schott North America, Inc. recently announced that its Supremax 33 rolled borosilicate glass is becoming the material of choice for glass for telescope applications. Supremax 33 glass, made by utilizing Schott“s unique rolling technology, replaces Pyrex from Corning, which is no longer available on the market. Some customers say that Supremax has an even better quality and clarity than Pyrex. Supremax 33, which shares identical properties of Schott “s floated borosilicate glass Borofloat 33, offers the qualities of low thermal expansion, high thermal resistance, excellent light transmission and impressive chemical durability. It is available in a new, wider range of thicknesses (up to 66.7mm), thus possible for telescope applications. Supremax is a highly versatile material suitable for an unlimited array of applications, thanks to its low density that makes it 12% lighter than soda lime glass. “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.”
