Request InfoThorlabs Inc.Volume phase holographic (VPH) gratings from Thorlabs Inc. are manufactured in-house for high first-order diffraction efficiencies across broad bandwidths and low polarization dependence loss. VPH gratings consist of a gelatin film with periodic index modulations that is sealed between two AR-coated glass substrates, providing low scatter of stray light between diffraction order peaks and minimal ghosting for use in spectroscopy and optical coherent technology applications. Customized round or square optics can be achieved with dimensions as small as 10 mm and as large as 60 mm. ...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra April 2023 IssueOptical Reference CavitiesThe XM-ORC series of optical reference cavities with crystalline mirrors from Menlo Systems GmbH and Thorlabs Inc. is stable at the zero-crossing of the thermal expansion coefficient.
