Request InfoValley Design Corp., HeadquartersValley Design Corp. offers a silicon carbide mirror finish. The company laps and polishes substrates and mirrors up to 12 in. in diameter to surface finishes better than 10 Å with l/4 flatness. According to the company, its light weight, high flexure strength, rigid structure and thermal properties make the material suitable for scan mirrors and movable optics for space telescopes. Silicon coatings that can be polished for an improved finish are also available.See full productRelated content from Photonics MediaPRODUCTSPhotonics Showcase September 2022 IssueThin-Film Re-Polishing ServicePG&O’s unique re-polishing service can salvage coated optics that have been damaged or the specifications haven’t been met during the thin-film coating process.
