Plane Holographic Reflection Grating, 12.5 x 12.5 mm, 250 nm, 1201.6 gr/mm

The 33025FL01-200H Plane Holographic Reflection Grating has 1201.6 grooves per millimeter and a nominal blaze wavelength at 250 nm. It has a recommended spectral region of 190 to 800 nm. This 12.5 x 12.5 mm grating is aluminum coated on a 6 mm thick float glass substrate. Newport Richardson Gratings' holographic gratings provide excellent wavefront flatness and high efficiency. Like their ruled counterparts, holographic gratings are most efficient when used in the Littrow configuration.
