Glass-ceramics for extreme temperatures
Auer Lighting offers special glass-ceramics for high-temperature lamps. With a coefficient of thermal expansion close to zero, reflectors made of this material can easily be used for the increasing number of high-performance lamps. They withstand extreme temperature shifts in operation without building up tension. We offer a wide variety of shapes and optical designs tailored to all kinds of specific demands.
