MidOpt BN940-35.5 Narrow Bandwidth NIR Bandpass Filter

BN940 Narrow NIR Bandpass filters feature a narrow band design with improved blocking of unwanted light and more incredible insensitivity to short shifting. These make them particularly essential when 940nm lighting is used with a short focal length camera lens.

940nm LEDs are commonly used in remote control devices and security/surveillance lighting. 940nm illumination is often considered “covert,” as little, if any, faint red glow is produced from these LEDs, even in complete darkness. Unfortunately, CMOS and CCD cameras have greatly reduced sensitivity at these wavelengths, and strong ambient light can often make imaging in this range very difficult.
