Using 0.21mm flat glass, a bandpass spectrum of 940nm or customer required is plated by sputtering in order to filter all but the specific spectrum. At the same time, the center wavelength offset of A.O.I0 ° ~ 30 ° is less than 10nm.
Technical characteristics and advantages:
Nanoscale precision filters
High SNR (signal-to-noise ratio)
Strong anti-interference ability
Mobile phone approaching light sensor
3D camera transmitting and receiving module
