Description
The 850nm band-pass filter is used in NIR imaging system to eliminate the influence of surrounding background light, including the visible and NIR. This filter is to increase the signal/noise ratio of the imager. The applications include secure monitoring, visual telephone, visual doorbell, digital telescope and other imaging systems.
Band-pass 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 band-pass optical filters and narrow band-pass filters are coating on transparent optical glass or colored optical glass
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, BK7， Float glass
IR sensor IR CCD Camera
We focus on designing, developing and manufacturing various applications of Infrared (IR) thin film coatings
