Smart Hyperspectral Imaging Camera

The EVK HELIOS NIR G2-320 hyperspectral imaging system is a powerful classification system, based on non-contact and non-destructive infrared imaging spectroscopy. The EVK HELIOS NIR G2-320 Class delivers a classified data stream for analyzing and monitoring applications in-line and at-line. The EVK HELIOS system analyzes the chemical properties of objects and makes the distinction of material types not visible to colour cameras. The internal classification engine delivers qualitative and quantitative information of material streams.

EVK HELIOS NIR G2-320 Class, the smart Hyperspectral Imaging analysis and sorting system is available in the wavelength range of NIR (0.93 µm – 1.7 µm). EVK HELIOS cameras have no moving parts and are therefore robust enough to tolerate even the most demanding industrial applications.


Spatially resolved NIR spectroscopy in real-time

The high frame rate hyperspectral camera EVK HELIOS NIR G2-320 Class delivers 320 pixels of spatially resolved spectra at 500 Hz in a line format. The integrated real-time classification engine processes camera data streams and outputs false colour RGB images for further processing. Through an integrated modelling workflow, our customers can quickly develop and adapt EVK’s camera systems to any application. CORE cameras output raw hyperspectral images for external spectral processing.

The open-format GigE-Vision/Gen<I>Cam ports make EVK HELIOS NIR cameras a robust and highly adaptable industrial component for any sorting or inspection system.

EVK HELIOS NIR G2-320 Class cameras do not require an external PC during operation – they are standalone devices. All cameras are calibrated and free of spatial or spectral distortions. The standardisation of cameras allows all EVK cameras to be quickly exchanged if required.
