Request InfoVincent AssociatesVincent Associates has announced three additions to its Uniblitz N-CAS DSS (design scalable shutter) series: the 10-mm-aperture DSS10, the 20-mm-aperture DSS20 and the 25-mm-aperture DSS25. The patent-pending devices have flat mounting surfaces on both sides and have no external actuator or other interfering components, allowing flush mounting. Drive and damping components related to the mechanical motion of the shutter are contained or integrated within. The only moving parts are the drive ring and the blades, limiting points of wear. A circular envelope with a concentric aperture enables...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 4/2/2024Optical Transport SolutionsThe optical transport solutions from Nokia are meant for optical transport, IP routing, and PON applications and include coherent optical transceivers, a photonic engine, and a multihaul transceiver....Photonics Spectra November 2022 IssueRadiation-tolerant LensesResolve Optics Ltd. has announced 1080p, high-definition resolution lenses optimized for a new generation of radiation hard CMOS cameras.
