SWIR Cameras

Short-wave Infrared (SWIR) is similar to visible light in that photons are reflected or absorbed by an object, which provides the strong contrast required for high-resolution imaging. SWIR cameras with indium gallium arsenide (InGaAs) sensors have a number of interesting applications as they can image through fog, water vapor, and certain materials, like silicon. They can also help differentiate between colors that appear identical in the visible spectrum. SWIR line scan cameras can be used in a variety of inspection applications; such as detecting foreign contaminants like twigs, plastic, and screws, in a food product stream; identifying bruised fruits by detecting moisture content; imaging through silicon to detect cracks and saw marks on wafers; seeing through pharmaceutical pill packs to ensure each is filled; and more.
