DB660/850 Dual Bandpass Red + 850nm NIR

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 color rendition while retaining the ability to pass a specific LED or laser diode wavelength used for nighttime illumination. Useful Range : 645-675nm, 830-870nm FWHM : 40nm, 50nm Tolerance : +/-5 Peak Transmission : ≥90% Surface Quality : 40/20 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
