The 77941 Flat Ruled Grating is fabricated from a N-BK7 glass substrate and coated with an AlMgF2 broadband reflective coating. This 30 x 30 x 3 mm grating has a 300 l/mm line density, and a 2000 nm blaze wavelength and 90% peak efficiency at the blaze wavelenth. This grating's efficiency exceeds 20% over the 1100 to 5000 nm primary wavelength region.
