Low-Expansion Glass Ceramic “TCM”
“TCM” is glass ceramic with low thermal expansion and excellent heat resistance characteristics. “TCM” was originally developed for high power projector lamps and is widely used for projector lamps for many years. “TCM” glass ceramic can be utilized for high heat resistance applications other than projectors.
