                                                   Optical glass

Baode optical glass supply optical filter from 200nm to 2500nm.The optical glass is the glass material used in the lens, prism, reflector and windows of optical instruments and optical equipments. The various kinds of optical glass are as the follows: Uncolored optical glass, colored optical glass, laser glass, radiation resistance laser glass, radiation protection laser glass and quartz glass. The uncolored optical glass is commonly regarded as the optical glass, which is one of the general specifications in glasses. Optical glass has color optical glass and colorless optical glass.      cut-off type: block the short wavelength by ab sorption and transmit the long wavelengthselective absorption type:transmission (or absorption) one wavelength (or several wavelengths)neutral density type:similar absorption for the whole visible wavelength range.
