EVK HELIOS HSI Laboratory Station

EVK HELIOS Laboratory Stations are hyperspectral imaging systems designed to classify materials based on their chemical composition.
The all-in-one hyperspectral imaging system is ideal for developing industrially applicable chemometric models, for use in the lab, 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.


EVK Helios
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 a conveyor belt. The hyperspectral camera is a line scan camera that measures in the wavelength range from 930 to 1700 nm. EVK HELIOS laboratory stations are available as CORE or CLASS models.

The EVK HELIOS Laboratory Station Core has an EVK HELIOS EC hyperspectral camera and is ideal for capturing high-quality spectral data used in laboratory testing or for flexible use with your own analysis tools. Develop algorithms based on spectral data and export acquired data to common data formats (Matlab, CSV,..). External calibration is not necessary.

The EVK HELIOS Laboratory Station Class includes an EVK HELIOS EQ hyperspectral camera equipped with an integrated classification system. This station is ideal for fast and straightforward application testing and at-line quality control.

Your hyperspectral imaging station to create chemometric models, use in lab and for at-line inspections

EVK HELIOS Laboratory Station features a motorized table with adjustable speed, imitating 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.

Value Statements

All-in-One Hyperspectral Imaging System

The compact design includes all components required to quickly create chemometric models, use flexibly in lab, or at-line inspections.

Fast Setup and Data Acquisition

The straightforward setup and the qualitative and quantitative data analysis software EVK SQALAR allow easy data collection and analysis.

Height-Adjustable Mount

The height-adjustable mount makes it possible to conveniently adjust the distance between the camera and samples to test different configurations.

Flexible Application Options

Selecting between the core and class hyperspectral camera gives you the flexibility to use the EVK HELIOS laboratory station to develop your own analyses and models, or measure individual samples from the material stream with our complete system.


Developing Models with the
EVK HELIOS Laboratory Station

Hyperspectral cameras record each point in an inspection line in the short-wave infrared wavelength range from 930 nm to 1700 nm. This range is excellent for material identification, allowing precise surface measurements. Hyperspectral imaging makes it possible to the classify objects based on their chemical composition, visually represented thanks to false-color images. Combined with the analysis software EVK SQALAR, you can perform qualitative and quantitative analyses and, if desired, takes the created models directly into the production line. The HELIOS Laboratory Station is used to configure and test new applications. For our customers, the station offers a compact setup designed for at-line inspections, measuring samples, creating new chemometric models, and use in lab.

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. A precise approach is required for data acquisition to ensure the best possible results, 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 you the support of our experienced EVK professional services team. To optimally develop models, the samples are chosen and prepared so that they cover all material fractions while minimizing external influences such as rolling, sliding, or shifting. All data are stored on a PC connected to the EVK HELIOS. Customers can use this data to create models independently. After developing a satisfactory model, it can be transferred to the customer’s production line in the next phase.

Typical Applications of the HSI Laboratory Station

The EVK HELIOS Laboratory Stations are used for creating industrially applicable chemometric models, to use in lab 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.

  • Material Classification
    The EVK HELIOS Laboratory Station plays a crucial role in developing models 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 to analyze materials in detail, classifying objects based on specific values such as the degree of ripeness, moisture content, or pH value. Algorithms developed in-house help to integrate quantitative analyses directly into the production line and measure chemical compound concentrations.
  • Feasibility Studies
    The EVK HELIOS Laboratory Station is also used for feasibility studies to test whether hyperspectral imaging is a good fit for specific applications. The necessary parameters are defined, and test material is examined either in EVK’s technical center or on site. Following our investigation, you will receive a detailed proof-of-concept report.
