Request InfoMeller Optics Inc.Meller Optics Inc. has announced a line of optical lapping pitch made from wood resin rather than from petroleum by-products. The pitches provide a fine finish and prevent contamination of the polishing media or substrate. Five grades -- from very soft to very hard -- are available, as are melting points ranging between 52 and 87 °C. The company says that different batches are extremely uniform and that the hardness grades are all compatible. The pitch comes in 1- and 5-kg containers and requires no screening, filtering or additives. The user slices the required amount, melts it and pours...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Nov/Dec 2023 IssueSapphire and Ruby BallsThe Meller Sapphire and Ruby Balls from Meller Optics are miniature high-precision sapphire and ruby balls for use as bearings and mechanical components in medical and scientific instruments and as...Photonics.com 7/15/2022Sapphire WaveplatesSapphire Waveplates from Meller Optics Inc. can convert the polarization state of laser light into a different polarization state.
