Optical Filter>Bandpass Coating Filter

850nm bandpass filter

¡¡

 Application:
CCTV camera,video doorbell,surveillance camera,digital telescope,IR receiver,telemetry controls,laser rangerfinder,laser speed measurement,biological detection,projector,Fingerprint Identification System,Human Face Identification System,Barcode Scanner
Substrate:B270,Sola-lime glass,BK7

Bandpass filters are designed to isolate a region of the UV,visible,infrared spectrum. This is accomplished using a complex process of constructive and destructive interference.Band pass filters have bandwidths (measured at half-peak transmittance levels) less than 6% of the center of wavelength value.Our bandpass optical filters and narrow bandpass filters are coating on transparent optical glass or colored optical glass

CWL means center wavelength, FWHM means full width at half maximum
