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 MediaPRODUCTSPromoted Content October 2022 IssueIR FiltersDSI designs and manufactures thin film coatings such as bandpasses, beamsplitters, ARs, and absorption coatings for use in the MWIR thru LWIR wavelength regions.
