Plane Ruled Diffraction Gratings

The groove spacing and blaze angle determine the distribution of energy for a plane ruled diffraction grating. The blaze direction for most gratings is specified for first order Littrow use where light is diffracted from the grating back toward the source. This configuration offers maximum efficiency, or blaze, at specific wavelengths. The gratings shown below are made from our most popular master gratings and are typically in stock. Plane ruled gratings from over 100 masters are availaible. Please view our build-to-order plane ruled grating guide for our complete offering.
