The MidOpt LP347-25.5 NIR window is an anti-reflection-coated window specifically optimized for near-infrared transmission while allowing visible light to pass. These windows are made of optically ground, polished, and coated B270 crown glass and are commonly used as protective cover glasses for cameras used in surveillance, LPR/ANPR, and security applications that operate primarily in the dark with the aid of infrared light sources. All MidOpt filters can also be purchased unmounted and in custom dimensions upon request from Machine Vision Direct.
