Colored optical glass

Colored optical glass is intended for manufacturing of light filters with differential absorption of light emission within wavelength broad band. This light emission is formed by large thresholds in various regions of spectrum, narrow and diffused absorption bands and defined by nature of color center, i.e. different types of electronic transitions.

LZOS Company manufactures the following group of colored optical glass: yellow (ZC group), orange (OC group), red (KC group), infrared (IKC group) and colorless (ultraviolet) glass (BC group).

Colored optical glass is made in form of blanks (diameter and length of the most side) is less than 400mm.

The list of colored optical glass and ranges of application of color light filters are as follows in tables below.
