Highlights The DB550/850 compliments the DB660/850 and DB475/850 filters. When modifying a single color camera by removing its IR blocking filter, incorporation of this filter in its place allows reflected near-infrared light (850nm) to be captured in the camera sensor’s red channel and reflected green light (550nm) to be captured in the sensor’s green channel … Continued
A DB940 filter passes visible and 940nm LED light. 940nm LEDs do not emit the faint red glow associated with 850nm and other lower near-IR LED wavelengths. Using a DB940 filter over or behind the lens allows full color imaging during the day and covert surveillance at night. However any cameras spectral response at 940nm … Continued
A DB850 filter passes visible and 850nm LED or laser diode illumination. 850nm LEDs are perhaps the brightest of all infrared LEDs. Using a DB850 filter over (or behind) the camera lens allows for full color imaging by day and excellent monochrome contrast at night. Useful for machine vision and day/night surveillance applications.
DB735 filters pass visible light and 735-740nm LED light. These filters allow maintenance of excellent color rendition while taking advantage of any cameras significantly higher spectral response at lower near-infrared wavelengths. Useful for license plate recognition, traffic control, surveillance and machine vision applications.
The DB660/850 filter has been designed primarily for NDVI imaging applications. When using a single camera, incorporation of this filter allows reflected red light (660nm) to be captured in the camera sensor’s red channel and reflected near- infrared light (850nm) to be captured in the sensor’s blue channel (the green channel is not used). Even … Continued
The DB475/850 Dual Bandpass Filter has been primarily designed for NDVI imaging applications. When using a single camera, incorporation of this filter allows reflected near-infrared light (850nm) to be captured in the camera sensor’s red channel and reflected blue light (475nm) to be captured in the sensor’s blue channel (the green channel is not used). … Continued
