Short-wave infrared imaging (SWIR) is an advanced technique that generates images from the electromagnetic spectrum invisible to the human eye, generally defined as light in a wavelength range of 0.9 – 1.7μm but can also range from 0.7 – 2.5μm. SWIR cameras are imaging systems that are compact, portable, and offer precise detail from color measurements to advanced chemical imaging.
SWIR light behaves like visible light by reflecting off objects, which causes shadows and contrasts in images. The resolution and detail of SWIR camera images are comparable to those of visible images, making it easier to differentiate objects in a region even if they are similar in color.
SWIR cameras are popular in various industries because of their capabilities, which make them valuable. They are commonly used for night vision, inspecting internal structures, and seeing through smoke, low light conditions, and other materials.
SWIR Camera Recommendations and Applications
SWIR cameras have diverse purposes due to their technology and have an abundance of advantages when used in industrial environments.
