#F2F3F2 LP347 Near-IR Protective Window

LP347 Near-IR Windows are antireflection coated windows that are optimized for near-infrared transmission, while still allowing visible light to pass. Commonly used as a protective cover glasses for cameras used at night in surveillance, LPR/ANPR and security applications, these windows are made of optically ground, polished and coated B270 optical crown glass. This results in no image distortion and excellent transmission across the entire near-infrared spectrum that monochrome CMOS/CCD cameras are most sensitive to. They are environmentally stable, stain-resistant and cosmetically superior. These durable broadband, multilayer anti-reflection coatings limit glare and other reflection losses in the near-IR while helping to achieve optimal image quality.
