Chemic Inspector

Hyperspectral imaging equipment for quality inspection

Chemic Inspector analyses any type of raw product, being suitable for all types of products.  It is a quality inspection equipment designed to verify the correct chemical composition of the products by means of hyperspectral vision and chemical images.

The equipment is also capable of checking the presence of any surface chemical compound, being able to classify the product typology according to its chemical composition and detect contamination. The equipment incorporates a patented lighting system that allows the capture of linear hyperspectral images at high speed.

What are the advantages?

Detection of defects so far invisible to vision systems

Classification according to surface chemical composition

Quality classification by chemical image processing

Adaptable to any production plant

Great versatility in the typology of products analyzed


The equipment composes chemical images based on hyperspectral imaging in different bands of the infrared spectrum (VNIR, NIR, SWIR…)

Chemic Inspector has extensive image processing capabilities that allow chemical composition analysis by in-line mass spectrometry.

  • High-speed hyperspectral image capture and processing
  • Parallel generation of different chemical images
  • Classification of products and detection of quality defects by chemical composition
  • Detection of invisible foreign bodies




Its advanced technology allows it to process images not only within the visible range, but also in the SWIR range, using hyperspectral vision technology, which represents a technological and performance leap compared to conventional inspection systems.

A hyperspectral image is an image with different spectral bands of information across the entire electromagnetic spectrum. The pixels are defined according to the bands that have been observed, that is to say, they will have as many values as bands. The techniques for forming these images divide the spectrum into bands that extend beyond the visible.

The hyperspectral vision allows the detection of microorganisms in food or foreign bodies, thus avoiding the use of complicated laboratory tests.

Hyperspectral vision technology is a technique with multiple applications since it combines spectroscopy and image analysis, contributing to the effectiveness of quality control processes in the food industry where it is essential to know this kind of factors in real time.

The hyperspectral linear lighting system is a patented system that allows the capture of images at high speed. Its light beam concentration system allows continuous operation without causing the equipment or the products being inspected to heat up.

The lighting system is designed for each range of the visual spectrum, with an LED option for the NIR spectrum and a linear halogen light source for the SWIR spectrum.

All the elements of the system are designed to obtain a long durability and to be compatible with the requirements of the food and pharmaceutical industry.

The equipment integrates a chemical image composition software developed by INSPECTRA, which allows to automatically perform quality control tasks at 100% of the production in line with the process.

The chemical image allows to obtain a composition map (density, humidity, fat, protein, etc.) in real time of the food or product that is being analysed. In other words, it shows images where the concentrations of the parameters that we are interested in analysing appear at each point of the food. It is used both in analytical process controls and in quality controls.

In addition, the chemical image allows the detection of foreign bodies that may appear in the production line, so that they can be rejected and separated from the correct product.

The great advantage of this technology is that it can process images in both the visible and near-infrared ranges, with various inspection speeds and widths, which means that it can be adapted to any product.

It is an innovative technology based on spectral vision, which covers the limitations of conventional vision inspection systems used so far in the food industry.
