Shortwave Infrared (SWIR) wavelength band offers unique imaging advantages over visible and other thermal bands. It is quietly earning a growing place in industrial machine vision for electronic board inspection, material/food sorting, solar cell inspection, quality inspection, and in military applications. SWIR lenses are utilized where other detectors or cameras are not sensitive enough for finite detail recognition.

Short-wave infrared (SWIR) light is a second of the electromagnetic spectrum typically in the 0.9μm to 2.5μm (900nm to 2500nm) wavelength range and is therefore invisible to the human eye.

However SWIR light interacts with objects in a similar manner to visible wavelengths in that photons are reflected by the object itself. As a result of this reflective nature, SWIR light has contrast and shadows in the images it produces which are a necessary requirement for high-resolution imaging.

SWIR is unlike Mid-Wave Infrared (MWIR) and Long-Wave Infrared (LWIR) light, which is emitted from an object as thermal IR (heat) and therefore has lower resolution and shows less detailed images.

SWIR wavelengths can only be seen by sensors such as Indium Gallium Arsenide (InGaAs). Images from InGaAs camera sensors are comparable in detail and resolution to visible light images but are not in color. This is one of the many advantages of SWIR as it allows objects to be more easily recognized and individually identified.
