Optical Filters and Specialty Glasses
Near Infrared (NIR) Absorptive Filter
SC807 Series
- NIR absorptive filter is equipped with solid-state image sensing devices, such as CCD or CMOS, so that natural and accurate colors are produced. Our absorptive filters are ideal bandpass for visual areas when high absorption in the near infrared (NIR) wavelength range is required.
- SC807 Series includes three types, SC807, SC807H, and SC807L, by the difference in transmitting wavelength range.
- SC807 Series are weather-resistant, designed to perform in difficult environments, and have higher absorptive NIR ability compared to conventional products.
