Short Wave Infrared Camera

SWIR Vision

We highly suggest you take a look into what Infrared cameras are all about! 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 provide excellent quality.

SWIR Imaging

SWIR imagers offer use in a great amount of applications. 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. Short Wave Infrared cameras will only be used more frequently as time goes on and technology advances.

Machine Vision Imaging

Machine vision imaging is a very popular application for SWIR. 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. We love the use of machine vision imaging for quality control.

NIR Cameras

Another type of Infrared camera that has a great number of potential uses and applications is known by the acronym NIR. Near-infrared (NIR) is the portion of the electromagnetic spectrum directly adjacent to the visible range; thus 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 quit working when they reach their own limits. 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. You may find a short wave infrared camera to fit your needs better.
