DB850 Dual Bandpass Filter Visible + 850nm NIR

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. Useful Range : 405-645nm, 835-875nm FWHM : 250nm, 50nm Tolerance : +/- 20nm Peak Transmission : ≥90% Surface Quality : 40/20 Compatible LED : 840nm, 850nm Features •Pass visible light and a specific narrow IR band •Peak Transmission > 90% •Ensure that precise, high-contrast images are obtained during both day and night observation. •Achieve accurate color rendition by blocking interfering wavelengths •Allow viewing a scene with appropriately matched IR illumination at night •Useful for video security, red light camera, game camera and license plate recognition applications. Mount & Size Options •Threaded Mount, C/CS Mount, Slip Mount, Unmounted •Threaded Mount Sizes: M22.5-M82 •Custom sizes and shapes available Visible + IR Ideal for applications that use a color camera, allowing for accurate color images during the day and monochrome or color images at night. These filters pass visible light and a narrow IR band that make viewing with commensurate IR illumination possible at night.
