Abstract

See full text

A method for forming an optical window. In one example, the method includes depositing a layer of eutectic bonding material onto a first surface of a first section of window material, positioning a second surface of a second section of window material onto the layer of eutectic bonding material such that the first surface is disposed opposite the second surface, and heating the eutectic bonding material to a temperature above a eutectic temperature of the eutectic bonding material and below a melting temperature of the window material for a predetermined length of time to form an optical window. The window material of the first section and the second section may be transparent to infrared radiation and comprise aluminum.
