EVK Helios - Model NIR G2 320 Core -Hyperspectral Imaging Analysis and Sorting System
EVK Helios, the smart Hyperspectral Imaging analysis and sorting systems are available in two wavelength ranges: NIR (0.9 µm – 1.7 µm) and SWIR (1.0 µm – 2.5 µm). Each wavelength range is suitable for particular sorting applications. HELIOS cameras have no moving parts and are therefore robust enough to tolerate even the most demanding industrial applications.
- Real-time hyperspectral imaging system
- 320 pixels spatial resolution in NIR wavelength band
- High quality optically corrected spectra
- Classified data stream
The EVK HELIOS hyperspectral imaging camera is a powerful classification system, based on non-contact and non-destructive infrared imaging spectroscopy. The HELIOS NIR G2-320 delivers a classified data stream for analyzing and monitoring applications in-line and at-line.
Due to the HELIOS system analyzes chemical properties of objects and makes distinction of material types not visible to color cameras. The internal classification engine delivers qualitative and quantitative information of material streams.
EVK HELIOS NIR G2 320 high frame rate hyperspectral camera delivers 320 pixels of spatially resolved spectra at 500 Hz in a line format.
For CLASS cameras, an 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.
For both camera types (CORE and CLASS), open-format GigE-Vision/Gen<I>Cam ports make HELIOS cameras a robust and highly adaptable industrial component for any sorting or inspection system.
Helios 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.
