EVK Helios
EVK HELIOS hyperspectral cameras support current industry standards and ensure reliable and continuous monitoring and sorting in real time. The line scan cameras measure in the NIR wavelength range from 930 nm to 1700 nm, which is particularly useful for material identification. The robust design has been specially developed for use in demanding industrial environments. EVK HELIOS is available in CORE (EC) or CLASS (EQ) versions.

EVK HELIOS EC Core cameras are ideal for capturing the unique spectral signatures of materials. In combination with the EVK ALPHA data processing platform, they are a powerful system for industrial applications or for testing purposes in the laboratory. The EVK HELIOS EC is suitable for flexible use of custom models and provides optically corrected spectral data. External calibration is not necessary.
EVK HELIOS EQ Class cameras also have an integrated classification function that uses multivariate spectral data analysis techniques to classify a material stream in real time. As an all-in-one device, EVK HELIOS EQ cameras are perfect for quick and easy integration into your system.
Precise material analysis and classification in real time
Our hyperspectral imaging systems are a reliable and precise tool for monitoring and sorting industrial material flows. Thanks to this non-contact, non-invasive method materials are analyzed and classified based on their chemical composition.
This makes it possible to qualitatively and quantitatively measure properties such as protein, fat, sugar, salt, starch, moisture, oil, or calorific value directly in the production line.
Value Statements
Automated Continuous Operation
The EVK systems replace and optimize previously manual, error-prone sorting of materials or time-consuming laboratory analyses. Save time and money through automation and increase your product quality at the same time.
Excellent Signal-to-Noise Ratio
EVK HELIOS hyperspectral cameras have an excellent signal-to-noise ratio, providing necessary key data in real time. While typical features such as spatial resolution (number of pixels) and frame rate are often used for comparison, response speed and signal-to-noise ratio are crucial, especially for high-speed applications that require high illumination levels and short exposure times.

EVK IRIL
EVK IRIL is an illumination unit specially designed for use with hyperspectral cameras. The illumination is one of the central components of a spectrometric setup. The unit projects a line-shaped light beam onto the conveyor belt or slide, providing a perfectly balanced light intensity for optimal image quality. The EVK IRIL lighting units are available in different lengths and can be flexibly combined. Heat dissipates passively through the cooling profile.
Hyperspectral camera lens
Choosing the right lens for an optical system improves the overall performance of the system. Many factors must be considered when selecting the right lens for a specific application, such as the lens mount, spectral range, focal length, working distance, object size and incidence of light.

How hyperspectral imaging technology works
As a pioneer of hyperspectral imaging (HSI) for industrial applications industrial applicationssuch as sorting and inspection solutions, we at EVK know what is important. EVK products have been successfully used in a wide variety of sorting and process monitoring systems worldwide since 2006.
Our line scan cameras use hyperspectral imaging technology to capture precise spectral information in a wide wavelength range. Unlike conventional image sensors, which only perceive three color channels, a hyperspectral camera can image hundreds of spectral channels. Hyperspectral sensors identify the material by its unique spectral signature and can classify or analyze objects by their chemical composition. Our hyperspectral imaging systems therefore offer a range of benefits for industrial image processing and quality assurance.
Quantitative Material Analysis for Industrial Applications
The EVK sensor systems were developed in close cooperation with partners from the mechanical and plant engineering sector and support machine learning. This has created a measuring system that is specially adapted for use in industrial working conditions.
Thanks to the EVK SQALAR software and specially developed algorithms, machine learning, and data processing for inspection, monitoring, and sorting, EVK HELIOS hyperspectral camera systems reliably detect and help remove unwanted objects from material streams. This real-time capability and robust design make the systems suitable for continuous 24/7 operation in industrial environments.
The quantitative analysis of materials in product streams opens up entirely new application options. Sorting decisions can be made in real-time directly in the production line based on referenced analysis values.
Sensor Fusion for Increased Purity and Sorting Accuracy
EVK makes it possible to combine data from various sensors, such as hyperspectral cameras, color cameras, or metal sensors, and extract key data from the results, forming the basis for further process-relevant decisions. Materials can be classified based on their color, shape, size, as well as their chemical composition and, if desired, sorted or distributed in real time.
