Request InfoDocter Optics Inc.Docter Optics Inc. introduces a high-performance line of off-the-shelf precision-molded B 270 glass aspheric lenses. They are designed to collimate or focus laser diode light as a single element and provide diffraction-limited performance for the 400- to 1200-nm wavelengths. The lenses can be obtained in diameters of 2 to 120 mm, with focal lengths of 3 to 239 mm, and with plano or spherical second surfaces. They also are available uncoated, or with single- or multilayer antireflection coatings.See full productRelated content from Photonics MediaPRODUCTSPromoted Content October 2022 IssueIR FiltersDSI designs and manufactures thin film coatings such as bandpasses, beamsplitters, ARs, and absorption coatings for use in the MWIR thru LWIR wavelength regions.
