  • Apparatus for copying holographic diffraction gratings
    Patent number: 4715670
    Abstract: An apparatus for copying holographic diffraction gratings comprises a coherent radiation source and, arranged successively one after another downstream the coherent radiation, a collimating system, a mirror, a master holographic grating, and a copy holographic grating. The master and copy gratings are rigidly secured to each other and face each other by their recording layers. The mirror is adapted for reciprocal travel along the length of the master holographic grating so that coherent radiation reflected by the mirror falls on said master grating.
