What Are SWIR Cameras?
SWIR cameras are specialized devices designed to detect shortwave infrared radiation (SWIR).
These cameras capture wavelengths that are longer than those of visible light. Although SWIR radiation is invisible to the human eye, it has various practical applications in industries where substances like water and heat exhibit higher absorption rates in the SWIR spectrum compared to visible light.
The operating principle of SWIR cameras is similar to that of regular cameras, utilizing imaging sensors like CCD or CMOS with structures adapted for SWIR detection. These cameras are employed in diverse fields, including manufacturing and agriculture, for tasks like product inspection and production line monitoring.
In the medical sector, they contribute to early cancer detection and medical device development. Additionally, the military uses SWIR cameras in night vision devices and underground exploration. A notable feature is their ability to observe objects with high absorption rates for substances like water and heat, which are otherwise invisible in the visible light spectrum. SWIR cameras also excel in capturing images in low-light or dark conditions.
