SWIR Vision Imaging
Infrared Imaging is actually very cool and complex! Did you know there’s different types of cameras? With infrared imaging, you have several different options to choose from for different applications. You may or may not have ever heard the acronym SWIR, but you should know that it stands for Short Wave InfraRed, and more often than not is going to refer 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. While LWIR imagers give off a lower quality image, SWIR provides a stunning, clear quality.
SWIR is used in application that require impeccable quality. Some of these applications are 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 intended 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 helps companies in their design and development of products? It is what helps cameras 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. The very last thing you as a business want to do is deliver an inferior product to the customer. Machine vision imaging really helps with quality control for brands.
Do you know how Near Infrared differs? 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 good lighting conditions to capture useable images. Setting up these light solutions adds tremendous cost and complexity, which in turn leads to rising system costs and deterioration of the price/performance ratio. Industrial cameras with NIR-optimized sensors greatly simplify life for manufacturers facing inspection tasks of this type.
