Although the terminology for the infrared range isn’t uniquely defined, it is widely accepted to use NIR for the wavelength range 700 – 1400 nm and SWIR for 1400 – 3000 nm.
Inspection, measurement and imaging in these IR wavelengths are every day more common and demanded, and make the NIR cameras and SWIR cameras (infrared cameras in general) a powerful tool in scientific and industrial applications.
Thermal cameras for thermal imaging and measurement are becoming an efficient tool for temperature measurements in industrial and research applications. The measuring range is typically 8 – 14 um.
Quality control and safety measurements in food, pharma or chemical industries are also great candidates for thermal inspection.
And also security. You might not know it but you are surrounded by IR cameras.
