Narrowband Hologram Filters (Notch-Filters) and Selective Mirrors



Computer-Generated Hologram Optical Elements (CGHOEs)

     CGHOEs are designed to control shapes of spherical and toroidal surfaces and virtually all types of aspherical surfaces, used in optical engineering, as well as the main parameters of centered optical systems. The use of CGHOEs can contribute to control with an interferometric accuracy.
     A CGHOE is a high optical grade glass substrate, whereupon annular hologram structures are made. As a rule, a CGHOE comprises a principal hologram and an auxiliary one, the latter being used to control the CGHOE spacing in the optical layout.

Holograms are quantity produced products manufactured at OJSC "NPO GIPO". We are able to apply this technology into your industry in a short space of time and train your personnel to use properly hologram elements, as well as we stand ready to exercise authors supervision.
     Engineering solutions, that are applied at OJSC "NPO GIPO" in the context of diffraction and aspherical optics, have been protected by inventors certificates and patents.
