 | |  | |  |
Chalcogenide glasses are glasses formed by mixing one or
more chalcogen elements (S, Se and Te) with one or more other
elements such as As, Ge, Sb, Pb, Bi and Ga, etc. The glasses
have high transparency in spectral regions from near IR to
long-wave IR, high refractive index (2.2 ~ 3.5), and low
thermo-optic coefficient dn/dT as well as good chemical
durability. The glasses can be used in infrared sensors and
infrared imaging system.
