801 - 900nm Bandpass Filter
801 - 900nm bandpass filters are designed to transmit selected near-infrared (NIR) wavelength bands within the 801nm to 900nm range (such as 808nm, 830nm, 850nm, and 880nm) while reducing unwanted out-of-band light.
Application:
- NIR LED and laser diode source cleanup for illumination, pumping, and sensing systems
- LiDAR, time-of-flight (ToF), and 3D depth mapping optical systems
- Detector-side NIR signal isolation before CMOS/CCD cameras, photodiodes, or avalanche photodiodes (APDs)
- Machine vision, surveillance, and biometric scanning (iris/facial recognition) under NIR illumination
- Near-infrared fluorescence emission collection and optical measurement setups
