Description:
NSG’s Transmission Grating is fabricated with the newly developed technology that combines Thin Film Filter with Deep Dry Etching to have high diffraction efficiency and low PDL. It is made from inorganic materials only (no polymer, no epoxy and no gelatins) for high environmental stability /durability and complies with RoHS 6/6. Go!Foton works closely with NSG to design and provide various types of gratings to match custom specifications upon request.
