What is SWIR?

Posted by Ruben on 20th Dec 2022

SWIR cameras, also known as shortwave infrared cameras, are cameras that are sensitive to wavelengths of light in the shortwave infrared (SWIR) spectrum. This spectrum is generally defined as the range of wavelengths from 1000 nanometers (nm) to 2700 nm.

SWIR cameras are used in a variety of applications, including military, industrial, and scientific applications. In the military, SWIR cameras can be used for night vision and target identification, as they can detect objects that are invisible to visible light cameras. In industrial and scientific applications, SWIR cameras are used for monitoring processes, inspecting materials, and detecting defects.

One of the main advantages of SWIR cameras is their ability to "see" through smoke, fog, and other obscurants that would block visible light. They can also detect certain materials, such as metals and plastics, that are difficult to distinguish with visible light cameras.

SWIR cameras are typically more expensive and less sensitive than visible light cameras, but they offer unique capabilities that make them valuable for certain applications.
