Short Wave Infrared Camera

SWIR Camera Systems

You need to have a good understanding of Infrared cameras before deciding which fits your needs best. Short Wave InfraRed, also known as SWIR, is more often than not referring to the wavelength band of light that sits between 900nm and 2500nm. Unlike Long-Wave Infrared (LWIR) light, which is emitted from the object itself, SWIR light is similar to visible light in that photons are reflected or absorbed by an object, giving you the strongest contrast possible, which you really need for high resolution imaging. For high definition imaging, we strongly suggest the SWIR.

Short Wave InfraRed Imagers

SWIR imagers have so many different applications that need to be considered when selecting this mode of imaging. When it comes to these applications, it may be including silicon inspection, laser beam profiling, hyperspectral imaging, chemical and plastics sensing, machine vision imaging, agricultural sensing, surveillance systems, and medical imaging. They give you the ability to see those super minute defects that you just can’t catch otherwise, and in some circumstances that’s the difference between life and death. They are also crafted for use in mobile phone facial recognition sensors, and autonomous vehicle imaging though obscured environments. We definitely see these becoming more and more a part of future technology.

Machine Vision Imaging

We believe machine vision imaging may be the number one SWIR application. Machine vision imaging necessitates cameras that can see the absolute smallest defects, see that at extremely fast frame rates, and a field of view wide enough to image a large area. SWIR cameras are compliant with the main vision software programs you’ll find out there. Manufacturing anything always has some unknown and risk to it. With so many steps to the manufacturing process, there’s always a chance for something to wrong and lead to you putting out some undesirable product.

NIR Cameras

NIR is the last type of camera we will discuss. It is different from SWIR and LWIR. Near-infrared, also known as NIR, is the portion of the electromagnetic spectrum directly adjacent to the visible range, meaning it is not visible to the human eye. NIR-optimized industrial cameras are popular for applications that need to utilize this wavelength range, mainly applications with poor light conditions, such as traffic monitoring or even security. Until now, these applications were only possible with infrared cameras with expensive CCD sensors. Some application fields and inspection solutions require NIR for high wavelengths as well as for normal lighting, to record high-contrast images. Standard industrial cameras quickly reach their limits in that particular scenario, since they require very great lighting to get useable images. Setting up these light solutions really tacks on major extra costs and makes the entire system much more complex. Short Wave Infrared Camera or any other type of camera will require a lot of research and understanding of which one is best for you.
