A DB850 filter passes visible and 850 nm LED or laser diode illumination. 850 nm 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.
