Plane Ruled Reflection Grating, 12.5 x 12.5 mm, 250 nm, 13° Blaze, 1800 Gr/mm

The 33025FL01-061R Plane Ruled Reflection Grating is 12.5 x 12.5 mm and 6 mm thick. The grating has 1800 grooves per mm a nominal wavelength at 250 nm, and a nominal blaze angle of 13°. 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.
