Request InfoMeller Optics Inc.Meller Optics Inc. has introduced low-order sapphire waveplates for changing the polarization state of high-power IR and visible lasers from linear to circular, and vice versa. The waveplates feature Moh 9 hardness and antireflection coatings on both sides, allowing fabrication from 10 to 30 mm in either A- or M-plane configurations. They are resistant to chemicals, scratching, shock and temperature fluctuations, and can be made to diameters as thin as 0.4 and <25 mm. Exhibiting 10-5 scratch-dig surface quality and ≤1 arcsec parallelism, the waveplates provide λ/4 and...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 7/15/2022Sapphire WaveplatesSapphire Waveplates from Meller Optics Inc. can convert the polarization state of laser light into a different polarization state.
