Low loss visible-IR transmitting glass-ceramic spinel composites and process
NRL
This invention pertains to a composite of Spinel and BGG glass substrates and to process for bonding Spinel to BGG glass. The composite includes a Spinel and a BGG glass bonded together and having transmission in the visible and mid-infrared wavelength region. The process includes the step of heating them together above the softening temperature of the BGG glass, the composite having excellent, i.e., typically in excess of about 80%, transmission in the 0.5-5 wavelength region.
