We specialize in optical filter.
Optical filter
Supply optical filter from 200nm to 2500nm.The optical filter glass is the glass material used in the lens, prism, reflector and windows of optical instruments and optical equipments. The various kinds of optical filter glass are as the follows: Uncolored optical glass, colored optical glass, laser glass, radiation resistance laser glass, radiation protection laser glass and quartz glass.
cut-off type: block the short wavelength by ab sorption and transmit the long wavelength
selective absorption type:transmission (or absorption) one wavelength (or several wavelengths)
neutral density type:similar absorption for the whole visible wavelength range.
