Dual Bandpass Filters

Dual Bandpass Filters
Dual Bandpass Filters are ideal for applications that use a color camera during the day and IR illumination at night – ensuring that clear, accurate images are acquired under all lighting conditions.
DB395/870 Dual Bandpass Absorptive Visible + NIR

DB395/870 Dual Bandpass Absorptive Visible + NIR

Please choose thread size. Prices starting at $68

DB395/870 Dual Bandpass Filter passes UV-Violet and infrared wavelengths, effectively blocking all green and red light. These filters have traditionally found use in NDVI-type imaging applications. When using a single camera modified for aerial agricultural surveillance, incorporation of these so-called “Superblue” or ...

DB475/850 Dual Bandpass Blue + 850nm NIR

DB475/850 Dual Bandpass Blue + 850nm NIR

Please choose thread size. Prices starting at $130

A Dual Bandpass Filter transmits two specific wavelength ranges while blocking shorter and longer wavelengths as well as some middle portion of the spectrum. These filters in particular pass visible light and some smaller portion of the near-infrared spectrum. Blocking most of the near infrared allows for excellent col...

DB550/850 Dual Bandpass Green + 850nm NIR

DB550/850 Dual Bandpass Green + 850nm NIR

Please choose thread size. Prices starting at $130

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 capture...

DB735 Dual Bandpass Filter Visible + 735nm NIR

DB735 Dual Bandpass Filter Visible + 735nm NIR

Please choose thread size. Prices starting at $68

DP735 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 ap...

DB850 Dual Bandpass Filter Visible + 850nm NIR

DB850 Dual Bandpass Filter Visible + 850nm NIR

Please choose thread size. Prices starting at $68

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...

DB940 Dual Bandpass Filter Visible + 940nm NIR

DB940 Dual Bandpass Filter Visible + 940nm NIR

Please choose thread size. Prices starting at $68

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 camera’s spectral response at 94...
