Do you know the differeces in Infrared cameras and how they have different applications in order to perform at their 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 the highest resolution imaging.
Short Wave InfraRed Imagers
SWIR imagers are used in many different applications and those applications continue to grow! When it comes to these uses, 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.
Machine Vision Imaging
Do you know what machine vision imaging is and how it ensures that products are developed without error? 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. There are just so many steps involved in most manufacturing processes, there’s always a chance for something to wrong and lead to you putting out some undesirable product. Delivering an inferior product to the customer could be very dangerous and lead to huge problems for your entire business.
NIR camers are 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. A professional in SWIR camera system could help you determine which is right for your needs.
