Color glass bandpass filter
PRODUCT CATEGORIES
- Color glass filter refers to the addition of special elements in the process of glass melting, so as to absorb different spectral bands and transmit the spectra of other bands.
- Due to the inherent absorption or transmission characteristics of the material, compared with the dielectric coated filter, the color glass filter will not change the central wavelength of the light beam incident at different incident angles. The color glass filter provided by United light technology has high durability.
