About Avantes
Avantes is the leading innovator in the development of fiber-optic spectroscopy instruments and systems, with nearly 30 years of experience developing customer-defined spectrometer configurations. Avantes spectrometers, light sources, and fiber-optic sampling accessories provide the enabling technology for spectroscopy and material characterizations in different markets and industries. We achieve this through service-oriented thinking and acting, encouraging and motivating each other with a positive, critical, and professional attitude. Our vision is to enrich the lives of humankind in the world we live in. Our mission is to provide state-of-the-art, innovative measuring equipment that helps humankind live longer and healthier and will save the planet for future generations.

Spectrometer calibration is an essential step for all spectroscopic applications. All our spectrometers are calibrated during production and quality control (QC). This process is carried out using calibration light sources with known spectral lines. During this process, light from a calibration light source (the choice of which depends on the configuration of the spectrometer to be calibrated) connected to the spectrometer, passes through various optical elements, including a dispersive grating, and eventually reaches the array detector. After calculating the peak position on the detector, the positions and intensities of the peak pixels are used to find the relationship between the position of the peak pixels and their wavelengths. This relation or wavelength calibration can be fitted by linear regression or low-order polynomial (or even 5th order, for example, by Bocklitz T., Dörfer T., Heinke R., Schmitt M., et al.). Recent publications also present wavelength calibration methods based on the physical model of the optical path in the spectrometer, as well as some improvements to the calibration procedure, e.g., using noise reduction, stray light removal, improved peak position estimation by peak shape fitting with Voigt function, Gaussian or Lorentzian, etc.

The goal of the internship is to propose an algorithm/model for a pixel-wavelength relationship, which suits the best to the available data. 

We offer:

  • A good compensation per month 
  • Travel reimbursement of €0,21 per km 
  • Informal work atmosphere, short lines of communication
  • Working in a high-tech environment
