Request InfoHeadwall Photonics Inc.The LPDL 900/1100 series holographic diffraction gratings developed by Headwall Photonics Inc. of Fitchburg, Mass., have a frequency of 900 and 1100 grooves per millimeter and 90 to 95 percent efficiency in both the TM and TE polarizations, allowing for higher dispersion -- and therefore higher channel count -- in a more compact package. Used in telecommunications equipment, the gratings deliver low polarization-dependent loss -- less than 0.25 dB for each polarization when used near the Littrow angle -- enabling higher signal strength without the need for complex and expensive...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 3/27/2024Extended C+L-Band GrismsCoherent’s family of aberration-correcting, high-efficiency grisms and transmission gratings encompass the entire extended C+L band in a single optic for the construction of compact network...Photonics.com 2/15/2023Spatial Light ModulatorsSpatial Light Modulators from Electro Optical Components Inc. use translucent and reflective liquid crystal micro-display technology to modify the amplitude and phase of incident light one pixel at a...Promoted Content September 2022 IssueBest-in-Class Spectroscopy is Just a Grating AwayThe grating used in a spectrometer design plays a defining role in its performance.
