Infrared cameras are used for image processing applications in the spectral range from 0.9 µm to 14 µm. This range is not accessible to the human eye. The long-wave ranges between 3-14 µm (MWIR and LWIR) are preferably used in thermal imaging in the medical field, rescue services or also for finding defects in electrics, electronics and construction, but also in research.
The short-wave infrared range (SWIR) of 900 - 2500 nm is particularly attractive for image processing. Imaging in this spectral range simplifies applications such as wafer and solar cell inspection, fruit sorting, plant growth monitoring or security feature detection.
The Ninox-640 is a cooled, high sensitivity digital VIS-SWIR camera.
The Acuros eSWIR VGA series from SWIR Vision Systems deliver crisp images in the range from 400 to 2100 nm. The cameras are designated EAR-99 requiring no license for export.
