Short-Wave Infrared

Short-Wave Infrared (SWIR) refers to a specific wavelength range from 1000nm to 1600nm. For reference, standard cameras usually operate between 0.4-0.75um (which is the visible spectrum). SWIR allows for a number of applications to be performed that were not possible using visible light cameras and with greater results.

In contrast to cameras on the visible spectrum, a SWIR camera has a lower refractive coefficient, meaning it is significantly less scattered and can sense what standard cameras in the visible spectrum cannot see. Thus, it makes the invisible become visible.
