Plane Ruled Reflection Grating, 12.5 x 12.5 mm, 1600 nm, 28.7° Blaze, 600 Gr/mm

The 33025FL01-550R Plane Ruled Reflection Grating is 12.5 x 12.5 mm and 6 mm thick. The grating has 600 grooves per mm a nominal wavelength at 1600 nm, and a nominal blaze angle of 28.7°. The diffraction grating is coated with an aluminum coating on float glass substrate and designed for first order Littrow use. Richardson Gratings' plane ruled reflection gratings have high efficiency in the spectral region around their blaze wavelengths. Ruled gratings are most efficient when used in the Littrow configuration.
