The 77906 Flat Holographic 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 1800 l/mm line density, and a 500 nm blaze wavelength and 80% peak efficiency at the blaze wavelenth. This grating's efficiency exceeds 20% over the 300 to 1100 nm primary wavelength region.
