Optical glass
A glass can change the direction of light propagation and the relative spectral distribution of ultraviolet, visible, or infrared light.
The narrow sense of optical glass refers to colorless optical glass;
The generalized optical glass also includes colored optical glass, laser glass, quartz optical glass, radiation-resistant glass, UV-IR optical glass,
fiber optical glass, acoustooptic glass, magneto-optic glass, and photochromic glass.
Optical glass can be used to make lenses, prisms, mirrors, and windows in optical instruments.
The components made of optical glass are the key components in optical instruments.
