Detailed Product Description
Colored Glass Filter (Color Filter)
It's fabricated by special color glass material. the material will absorption some wavelength and appeare different colors. The applications are including camerar filter, machine vision lens filter.
Material: Colored optical glass
1. Cut-off type: Block the short wavelength by absorption and transmit the long wavelength.
2. Selective absorption type: Transmission (or absorption) one wavelength (or several wavelengths).
3. Neutral Density type: Similar absorption for the whole visible wavelength range.
