By customizing the optical bandpass in the green light band to achieve green light transmission, the bandpass filters that cut off the rest of the light, and the matching process can be used to achieve assembly shipments.
Technical characteristics and advantages:
Bandpass position and bandwidth can be customized. Absorptive substrates such as blue glass can be used to achieve near-infrared deep cutoff.
With large-scale mass production and supporting performance
Fingerprint recognition module under optical screen.
