Request InfoEdmund Optics Inc.BARRINGTON, N.J., Sept. 15, 2011 — Ultraviolet transmission gratings manufactured from a UV-grade fused silica substrate have been announced by Edmund Optics. UV transmission gratings are relatively polarization-insensitive and fairly impervious to alignment errors for ease of use and for providing good light dispersal in a variety of fixed-grating applications. Intended for the 250- to 450-nm wavelength range, they are designed so that the incident light strikes the UV transmission gratings’ coarse groove spacing, where it is then dispersed to the opposite side of the grating at a fixed angle. As the groove...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 7/26/2022Optical MountsThe E-Series of Adjustable Size Kinematic Optical Mounts from Edmund Optics Inc. can be used for mounting a wide range of round, rectangular, and square optical components, including round and...Photonics Spectra December 2022 IssueNonpolarizing Cube BeamsplittersThe TECHSPEC® Nonpolarizing Cube Beamsplitters from Edmund Optics Inc. have a 50/50 reflection/transmission ratio and are constructed from high-tolerance N-BK7 right angle prisms.
