|The Wave Series cameras are dual-band line scan cameras capable of sensing Short Wave InfraRed (SWIR) light. The cameras are based on Indium/Gallium /Arsenide (InGaAs) sensor technology and JAI’s prism line scan technology, making them capable of delivering dual-band imaging in the SWIR light spectrum (900 – 1700 nm).
The new Wave Series camera brings dual-band imaging to the SWIR light spectrum to provide lots of extra “hidden” vision data. This capability can enhance current machine vision systems with imaging beyond what is possible when imaging the visible and/or the near infrared light spectrum. The Wave Series can open up a range of new applications in automated visual inspection.
Thanks to prism-based simultaneous image acquisition, it’s possible to precisely align images in two different spectral bands even when objects are moving at high speeds. The WA- 1000D-CL has a resolution of 2 x 1024 pixels and a maximum line frequency of 39 kHz.
The Wave Series opens up a range of new applications in automated optical inspection in areas such as the food industry for sorting and contamination detection, quality checks in pharmaceutical manufacturing, and potentially waste sorting applications.
The differences in light absorption levels -produce differences in darkness and brightness for specific objects or substances in the two images, which can be used as inspection criteria. This is best illustration by an image example: imaging of salt and sugar side by side.
Operation of the Wave Series camera is straightforward; no cooling is required and the data interface is standard Camera Link. The price level of the Wave Series line scan camera is lower than you may expect and the cost of ownership is comparable to a standard machine vision camera.
An advantage in SWIR is the variety of off-the-shelf optics available in comparison with MWIR cameras that require custom lenses and windows made of expensive materials.
