Newport offers a wide selection of Richardson holographic gratings with varying modulation depths. Generated optically, holographic gratings display none of the periodic errors or ghosts typically found in ruled gratings. Products typically exhibit excellent wavefront flatness and can have high efficiency in a single plane of polarization.
