Details

Transmission grating beamsplitters are commonly used for splitting He Ne laser beams and separating multiple lasers in the visible range. The transmitted light beam is diffracted into multiple orders. The transmission grating splitter is composed of a replicated layer of epoxy resin coated on a polished glass substrate with a refractive index matching it, in order to achieve higher overall diffraction efficiency. These beam splitters are specifically designed for He Ne laser beam splitting.
Guangtan Intelligent provides a variety of standard stock transmission grating spectrometers in sizes of 12.7mm and 25mm, with engraved lines of 70l/mm, 80l/mm, 92l/mm, and 110l/mm for you to choose from. If you have any questions or needs, please feel free to contact us and we will be happy to serve you.
Important Notice:The surface of the grating is prone to fouling and requires extreme caution when touched. Only touch its edges are allowed. Fingerprints and various aerosols can cause damage to the grating coating. Minor scratches or surface imperfections usually do not affect its optical performance. If you need to clean the grating, please consult first.
