We believe in Hyperspectral Imaging and Spectroscopy



Near-Infrared Spectroscopy (NIRS)

The near-infrared spectroscopy (NIRS) is a physical analysis technique in the short-wave infrared light range. Just like spectroscopy in the mid- and far-infrared range (MIR and FIR) it is based on infrared spectroscopy, but allows the use of other materials and light sources.

Infrared spectroscopy is based on molecular vibrations by electromagnetic radiation in the near infrared (760 nm - 2500 nm).

NIRS is particularly suitable for detecting organic compounds. Through specific markers also non-organic materials can be marked . Using NIRS one can generate a "fingerprint" for each material.

This results in different use cases which are described below.

Use cases are found in various industries


Spectroscopy allows the quantitative determination of water, which is bound in a substance. Applications are found predominantly in renewable resources such as e.g. coffee, wheat or tobacco.


NIRS can make products safer. Invisible markers allow backtracking and are effective against counterfeiters.


There is a wide range of applications in the industrial sector: the measurement of oils and lubricants as well as the analysis to evaluate surfaces are classic NIRS applications.

Life Sciences

By Life Sciences we understand all applications from pharmaceuticals to medical technology. With NIRS, for example, blood sugar or urine can be analyzed. E-Health does not stop with the fitness bracelet.


There are as many use cases as food diversity. With our technology the water content in honey or the sugar content of food can be measured. Meat is also very well suited for analysis using NIRS.


In the recycling process, the identification of plastics plays a major role. Polymers can be identified precisely with NIRS.


In agriculture, NIRS is used for soil analysis. Seeds or agricultural products are well suited for NIRS analysis.


Not only data from industrial cameras can be evaluated with hyperspectral algorithms. We are involved in various innovative projects that provide new impetus for classic industrial applications.

The BMBF funding project “FarmingIOS” was initiated by Photonics BW and is an example of the influence of photonics on many different areas of life and industries.
The project partners InMach Intelligente Maschinen GmbH, University of Tübingen and University of Hohenheim bring together expertise in the fields of agricultural science, software development, control system technology and robotics. This makes the project an excellent example of the use of optical technologies as key technologies in these industries. Through this interdisciplinary collaboration, the development of the new field of photonics in agriculture and the inclusion of innovative start-ups, the project also contributes significantly to the implementation of the cluster strategy of Photonics BW.
