Request InfoMeller Optics Inc.PROVIDENCE, R.I., March 23, 2010 – A low-cost line of sapphire wafer carriers perforated with custom patterns for vacuum hold-down or delamination and more durable than quartz and other materials (second only to diamond in terms of hardness, according to the company) is available from Meller Optics Inc. They are designed for thinning semiconductor materials, such as GaAs, and feature Moh 9 hardness. Sapphire offers good mechanical strength due to its off-axis crystal growth that permits custom fabrication of wafer carriers as thin as 0.4572 mm. Available with diameters from 50.8 to 152.4 mm, with flats and laser...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra November 2022 IssueIndustrial Microscope ObjectivesMXPLFLN series industrial microscopy objectives from Evident Scientific combine a high numerical aperture and long working distance for flexibility in various inspection applications.
