A method for bonding glass or metal fluoride optical materials to metal

摘要

The invention is directed to the use of energetic ion bombardment, in vacuum, to a surface of a metal fluoride crystal or optical element to remove contaminants on the surface and/or in micro-fractures. After cleaning, a suitable inert dielectric or metallic material is deposited onto the cleaned surface. A sealing agent is then applied to the inert material and a holder is placed about the entire assembly to hold and seal the metal fluoride element within the assembly. The method of the invention, and adhesion layer materials used in conjunction with the method, can be applied to glass elements as well as to metal fluoride single crystals and optical elements made from such crystals.
