Real time chemical imaging - Model EVK HELIOS EQ32 -0.9-1.7µm Hyperspectral Imaging System

EVK HELIOS EQ32, a measuring system with an integrated classification system specially designed for industrial working conditions, has been created in close cooperation with partners from the mechanical and plant engineering industry. Due to the stable optomechanical design for real industrial temperature conditions, machine designs and fields of application, as well as data processing and algorithms specially developed for analytics, EVK HELIOS EQ32 enables an optimized analysis directly in the process line.

• Quantitative and qualitative analysis of the data stream
• Real-time hyperspectral imaging system
• 320 pixels spatial resolution in the NIR wavelength band
• High quality optically corrected spectra
• Classifi ed data stream

Spatial resolution in real-time
The workflow in which the system is configured, chemometric models are created and transferred with the help of the software EVK SQALAR, is seamless. The evaluation takes place completely in the EVK HELIOS EQ32 system, whereby no external evaluation systems are required. However, a connection to already existing evaluation systems is easily possible via GigE Vision/GenICam and Camera Link. EVK HELIOS EQ32 is equipped with 312 effective pixels spatial resolution, measures in the wavelength range of 930 - 1700nm and thereby scans with a frame rate of 446Hz full frame.

Customers are supported by the EVK Professional Services team from application development to the fully integrated EVK HELIOS EQ32 system on-site. EVK thus enables the integration of state-of-the-art real-time analysis systems in the shortest possible time in order to successfully equip processing lines for the future and thus exploit the full potential of the applications.
