Visi-Lid™, an optical assembly, passes light at specified wavelengths. In its simplest form, the assembly consists of an A/R coated and glass metalized window of sapphire, silicon or germanium with a solder frame tack welded to the metalized portion.
More complex assemblies require the metalized windows to be sealed to a plated Kovar frame, with either a solder preform being tack welded to the Kovar frames or left bare for seam sealing. These assemblies hermetically seal various device packages.
