10HG2000-475-1 is a plane holographic reflection grating, with dimensions of 25 x 25 x 6 mm, 2000 grooves per mm and a wavelength of maximum efficiency at 475 nm.
Richardson Gratings' holographic gratings provide excellent wavefront flatness and high efficiency in a single plane of polarization. Blazed gratings are generated by bombarding holographically recorded masters with a beam of ions. This etching process alters the groove profile from sinusoidal to triangular, which often increases the peak efficiency of the grating. Like their ruled counterparts, holographic gratings are most effective when used in the Littrow configuration. is a plane holographic reflection grating, with dimensions of 12.5 x 12.5 x 6 mm, 1100 grooves per mm and a wavelength of maximum efficiency at 900 nm.
