940nm LEDs don't emit the faint red glow associated with 850nm and other lower near-IR (NIR) LED wavelengths
high-temperature environments
Near-IR (NIR) image sensors used together with 940nm illumination are also being used to support iris recognition in biometrics
frequently used in laser pointers and pattern generators
Narrow Near-Infrared (IR) Bandpass Filter, 730-755nm - MidOpt BN740 ND 940nm LEDs don't emit theThe MidOpt BN740 Narrow Near Infrared (IR) Bandpass Filter is commonly used in security, traffic control and industrial inspection applications when there is overwhelming ambient light conditions and is suitable for laser diode and LED illumination. MidOpt Bandpass Filters have a broad, Gaussian passband to mimic and accommodate the entire output of the most common LED wavelengths, are double side polished for exceptional parallelism and optical
