What Is NIR/SWIR Technology?

Near Infrared/Shortwave Infrared technology, deemed NIR/SWIR, extends Sensors Unlimited's standard InGaAs wavelength response down to 0.7 µm while still maintaining a 1.7 µm cutoff. Sensors Unlimted's standard InGaAs detector response runs from 0.9 µm to 1.7 µm. This extension allows for the sensor to detect standard military lasers currently used on the battlefield, while offering higher night vision sensitivity. Its original intent was to provide backwards compatibility to all military customers currently using intensified tube technology (i.e. I2CCD) or night vision goggle technology. NIR/SWIR still holds all the positives of standard operating InGaAs. For example, it can still image through haze and other obscurants; NIR/SWIR cameras can still detect eyesafe lasers. Simply put, it combines the best of InGaAs shortwave infrared imaging while covering the spectral range of night vision goggles. This provides the warfighter with the ideal set of capabilities at his or her fingertips. Ideal for integration into night vision and laser detection systems on unmanned aerial or ground vehicles, rifle scopes, precision guided munitions, and hostile fire indicators, NIR/SWIR is offered in our small, lightweight, high sensitivity KT camera platform. Potential industrial applications include machine vision to detect moisture, manufacturing imperfections, integrity of seals or joints, and other characteristics that affect product quality.
