The Blazing Of Holographic Gratings Using Ion-Etching

The development of holographic gratings has been significantly enhanced with the evolution of Ion-etching techniques to "sculpt" groove shapes in an effort to improve efficiency. In this paper it is shown that it is possible to create both plane and concave gratings with efficiency profiles consistent with classically ruled gratings. Success was achieved with gratings up to 110 x 110 mm in groove densities ranging from 300 to 2400 grooves per millimeter.© (1989) COPYRIGHT SPIE--The International Society for Optical Engineering.
