ultramarine glass filter

Selective absorption optical glass is an optical glass that can selectively absorb and transmit specific wavelengths in the ultraviolet, visible and infrared regions. This type of glass is usually called filter glass and is divided into three categories: selective absorption type, cutoff type and neutral gray.
