The 77962 Flat Ruled Grating is fabricated from a N-BK7 glass substrate and coated with an AlMgF2 broadband reflective coating. This 50 x 50 x 6 mm grating has a 400 l/mm line density, and a 1600 nm blaze wavelength and 85% peak efficiency at the blaze wavelenth. This grating's efficiency exceeds 20% over the 900 to 2900 nm primary wavelength region.
