Request InfoIDEX Health & Science - Semrock Optical FiltersA line of optical filters designed to efficiently combine or separate multiple laser beams has been launched by Semrock Inc. The LaserMux dichroic beamsplitters/combiners can multiplex 16 popular laser lines and can be used in reverse to demultiplex. Six filters for the nominal 405-, 440-, 488-, 514-, 561- and 635-nm wavelengths have been introduced. They are used at 45° incidence while maintaining a high degree of polarization insensitivity. The flatness ensures that there is less than one Rayleigh range of focal shift across a 2.5-mm beam diameter.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 3/27/2024Small Beamsplitter DetectorThe LIM-082 from InfraTec is a small beamsplitter detector in current mode that can be used in gas measurement technology.
