850nm NIR Band Pass Filter for ToF

850nm NIR Band Pass Filter for ToFAn 850 nm black glass filter is a type of filter product that meets high cut-off depth requirements among black glass optical and colored glass materials. It provides deeper cut-off performance in the blocking band and effectively filters out interfering light, achieving an ideal optical density (OD) range of 2 to 6 in the 850 nm wavelength region. This filter is commonly used in CMOS chip-based color cameras, CCD chip-based color cameras, security camera photosensors, black-and-white switching light barriers, surveillance (CCTV) cameras, video phones, video doorbells, network cameras, electronic toy cameras, and similar applications.Designed to transmit a narrow spectral band around 850 nm while strongly attenuating stray light, the hard-coated NBP850 filter enhances the signal-to-noise ratio for near-infrared (NIR) imaging and time-of-flight (ToF) depth sensing cameras. Modern indirect time-of-flight (iToF) systems typically operate at illumination…
