Color Glass Filter

Color Glass Filter is produced by doping special elements during glass melting, enabling it to absorb specific spectral bands and transmit target wavelengths. Featuring stable material properties, its central wavelength stays unchanged at different incident angles, delivering better angle insensitivity than traditional dielectric coated filters.
