Product Description

940nm IR Narrow Bandpass Filter

BN940 Narrow Near-Ir Bandpass Filters feature a narrow band design with improved blocking of unwanted light and greater insensitivity to short shifting, making Narrow Bandpass Filter particularly essential when 940nm lighting is used together with a short focal length camera lens.

940nm LEDs are commonly used in remote control devices and in 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.
