SWIR Shortwave Thermal Infrared Cameras

We at Infrared Cameras Inc manufacture components specifically designed, optimized, and coated for the SWIR wavelength range to ensure the highest resolution and lowest aberrations in our shortwave infrared (SWIR) cameras. These products use Indium gallium arsenide (inGaAs) sensor technolgy making them sensitive in the shortwave infrared spectrum ranging from 900 nm to 1,700 nm (0.9 μm – 1.7 μm).

Where Midwave Infrared (MWIR) and Longwave Infrared (LWIR) light is emitted from the object itself, SWIR is similar to visible light in that photons are reflected or absorbed by an object, providing the strong contrast needed for high resolution imaging. Some of the best SWIR images are captured using ambient star light and background radiance (nightglow), which are natural emitters of SWIR and provide excellent illumination for outdoor, nighttime imaging.

SWIR wavelengths transmit through glass, lenses, and other optical components (optical filters, windows, enclosures, etc.) allowing the components themselves to be manufactured using the same techniques for visible components, decreasing manufacturing cost and enabling the use of protective windows and filters within a system. This makes Shortwave (SWIR) infrared cameras the perfect choice for demanding and cost sensitive industrial applications beyond the visible spectrum.

SWIR Applications

SWIR imaging is used in a variety of applications including electronic board inspection, solar cell inspection, produce inspection, identifying and sorting, surveillance, anti-counterfeiting, process quality control, and much more.

A large number of applications that are difficult or impossible to perform using visible light are possible using SWIR. For example, when imaging in SWIR, water vapor, fog, and certain materials such as silicon are transparent. Additionally, colors that appear almost identical in the visible may be easily differentiated using SWIR.
