The 77972 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 150 l/mm line density, and a 1250 nm blaze wavelength and 85% peak efficiency at the blaze wavelenth. This grating's efficiency exceeds 20% over the 725 to 2800 nm primary wavelength region.
