EVK HELIOS HSI Laboratory Station
EVK HELIOS Laboratory Stations are hyperspectral imaging systems designed for material classification based on their chemical composition. The all-in-one hyperspectral imaging system is specifically designed for the development of industrially applicable chemometric models, for use in the laboratory, and for at-line inspections. The compact station consists of a small, button-controlled linear stage and an integrated EVK HELIOS hyperspectral camera, including a light system.

Laboratory Station
EVK HELIOS Laboratory Stations consist of a height-adjustable mount for the
EVK HELIOS hyperspectral camera, an illumination unit and a motorized sample table,
that imitates the function of a conveyor belt. The hyperspectral camera is a line scan camera that
measures in the wavelength from 930 to 1700 nm. The EVK HELIOS Laboratory Stations are
available in CORE and CLASS versions.

The EVK HELIOS Laboratory Station Core is equipped with an EVK HELIOS EC hyperspectral camera and is ideal for high-quality spectral data capture for laboratory testing and flexible use with your own analysis tools. Algorithms can be developed based on spectral data. Acquired data can be exported to common data formats (Matlab, CSV,..). External calibration is not necessary.
The EVK HELIOS Laboratory Station Class includes an EVK HELIOS EQ hyperspectral camera with an integrated classification system. This station is ideal for fast and straightforward application testing and at-line quality control.
Hyperspectral imaging station
for chemometric model creation, laboratory use, and at-line inspection
EVK HELIOS Laboratory Station features a motorized table with adjustable speed, imitating the function of a conveyor belt, and comes with two-sided illumination.
Due to the height-adjustable camera position, you can test different configurations and simulate in-line measurement conditions. Classified data can be easily accessed via the GigE Vision / GenICam interface.

Model Development with the
EVK HELIOS Laboratory Station
The hyperspectral cameras record for each location point in an inspection line in the short-wave infrared wavelength range from 930 nm to 1700 nm. This range is particularly well suited for material identification, allowing precise surface measurements. Hyperspectral imaging thus enables the classification of objects based on their chemical composition, visually represented through false-color images. Combined with the analysis software EVK SQALAR, you can perform qualitative and quantitative analyses and, if desired, transfer the created models directly into the production line.
The HELIOS Laboratory Station is used for configuration and testing of new applications. For our customers, the station offers a compact setup for at-line inspections, sample measurement, creating new chemometric models, or laboratory use.
Initially, the samples are placed individually or in groups on the EVK HELIOS Laboratory Station's sample table and captured by the camera. Depending on the task, quantitative or qualitative models are created based on the recorded data. To ensure the best possible result, a precise approach is required for data acquisition, as the inaccurate selection of pixels can negatively influence the result.
The selection and preparation of optimal parameters for the models often rely on empirical values, which is why we gladly offer the support of our experienced EVK Professional Services team.
For optimal model development, the samples are chosen and prepared to cover all material classes while minimizing external influences such as rolling, sliding, or shifting. All data are stored on the PC connected to the EVK HELIOS. Customers can use this data for independent model creation. After developing a satisfactory model, it can be transferred to the customer's production line in the next phase.

Typical Application Examples for the HSI Laboratory Station
The EVK HELIOS Laboratory Stations are used for creating industrially applicable chemometric models, for laboratory use, and at-line inspections. Our EVK Professional Service team can also develop models for your specific application or conduct a feasibility study for you. Simply contact us, and we will be happy to advise you on the possibilities.
- Material Classification
The EVK HELIOS Laboratory Station plays a crucial role in model development for industrial applications. Chemometric models for sensor-based sorting or monitoring applications can be created or further developed by classifying the materials. - Material Analysis
HSI laboratory equipment can be used for detailed material analysis, classifying objects based on specific values such as the degree of ripeness, moisture content, or pH value. In-house developed algorithms enable the integration of quantitative analyses directly into the production line and the measurement of chemical compound concentrations. - Feasibility Studies
The EVK HELIOS Laboratory Station is also used for feasibility studies to test whether hyperspectral imaging technology is suitable for specific applications. The necessary criteria are defined, and test material is examined either in EVK's technical center or on-site. Following this, you receive a detailed proof-of-concept report.
