- Commodity name: Transmission Grating Beam Splitter
Transmission grating beam splitters are commonly used for splitting He-Ne laser beams and separating multiple laser beams within the visible range. The transmitted beam is diffracted into multiple orders. Transmission grating beam splitters consist of an epoxy resin replication layer deposited on a polished glass substrate with a refractive index matching the substrate, thereby achieving higher overall diffraction efficiency. These beam splitters are specifically designed for He-Ne laser beam splitting.
