Dark NIR Glass Filter is of dark color NIR glass, which transmits the NIR light, but absorbs the visible light. With no coatings on the surfaces, it is perfectly used for IR protective glass in front of NIR imaging systems, or as a visible light reduction filter putted in front the LED light source. Compared to NIR acrylic filter, glass itself is with strong scratch and high temperature resistance for the best use in various rough environment. NIR glass usually requires the thickness at least 2mm in order to reach a deep blocking rate of visible lightrange.
