Request InfoMeller Optics Inc.Meller Optics Inc. produces ultraflat sapphire wafers for use as base plates for mounting substrates in semiconductor device manufacturing. The wafers have flatness to 0.5 fringes of HeNe and parallelism from 20 to 1 s, with ±1.2-µm piece-to-piece uniformity. The discs permit thin-film processing, can be polished on one or both sides, and are impervious to caustic etching agents. Transparent in the IR, the wafers are available with 50- to 82-mm diameters, tolerances to ±0.5 mm and thicknesses from 0.5 to 3 mm.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 4/8/2024Evaluation KitThe PyrIQ® Evaluation Kit from InfraTec supports the testing of digital detectors and IR source parameters without an otherwise required development of software, firmware, and test circuits....Photonics.com 4/14/2023Fixed Focal Length LensesThe EL5MP series of fixed focal length lenses from Opto Engineering are 5-MP optics for sensors up to 2/3 in. with integrated liquid lens technology.
