Technical parameter

The narrow bandpass filter BP850 dedicated to biological identification has a precisely locked central wavelength of 850nm (belonging to the near-infrared band). It is a key component for "optical signal purification" in biological identification systems, and its performance parameters are highly adapted to the strict requirements of biometric feature collection:

Narrow Bandwidth and High Selectivity: The Full Width at Half Maximum (FWHM) is usually controlled within 5-100nm,. It can accurately filter 850nm near-infrared light, effectively removing visible light and infrared light of other bands in the environment, avoiding interference of stray light on biometric imaging.

Fast Response and Stability: Adopting a high-stability dielectric coating process, within the normal operating temperature range of biological identification equipment (-20℃ to 60℃), the central wavelength drift is less than 1nm, and the transmittance fluctuation is less than 3%, adapting to the all-weather operation needs of fingerprint, face and other identification equipment.

Low Optical Distortion: The glass substrate is made of high-uniformity quartz or borosilicate material, ensuring no obvious phase shift or light spot distortion when near-infrared light passes through, and guaranteeing the integrity of biometric imaging.
