The seal goes on optical windows for protecting cameras, photodetectors, and imaging semiconductors such as CCDs, CMOS, and optical MEMS devices used in high-definition televisions. Leak tests on the glass-to-metal seal come in at less than 2 X 10 ¹⁰atm-cc/sec of helium. This is significantly lower than conventional sealing methods.
