Request InfoOptoSigma Corp.OptoSigma Corp. has developed a family of standard and custom parabolic mirrors, which are available in on- and off-axis configurations up to 16 in. in diameter. They are hand-polished from large blanks of fine-annealed low-expansion glass to precise focal lengths. Finished to a surface accuracy of 1/10 wave, the mirrors are supplied with a measured interferogram. Protected aluminum, enhanced silver, gold or broadband dielectric thin-film coatings are available.See full productRelated content from Photonics MediaPRODUCTSPromoted Content June 2022 IssueAR Conformal CoatingsDeposition Sciences’ exclusive IsoDyn™ low pressure chemical vapor deposition (LPCVD) technology is a high-temperature process that deposits extremely conformal coatings on a wide variety...Photonics Showcase January 2023 IssueContinuously Variable FiltersContinuously Variable Filters (CVFs) — also known as Linear Variable Filters — from Delta Optical Thin Film offer unprecedented tunability over a large wavelength range, steep filter...Photonics Showcase January 2023 IssueComplete Optical SolutionsPG&O’s complete turnkey optical solutions include high-precision surface quality on prisms and other optics from 0.059- to 30-in. diameter.
