Bandpass Filter
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.
Application:
CCTV camera, laser rangerfinder, laser speed measurement, biological detection, projector, Fingerprint Identification System, Human Face Identification System,Barcode Scanner, video doorbell,surveillance camera, digital telescope, IR receiver, telemetry controls.
Substrate: B270,Sola-lime glass,BK7
CWL means center wavelength, FWHM means full width at half maximum
