Spectrometers

VirtualLab Fusion enables, through the fast physical optics concept, the realistic analysis of spectrometers taking into account physical optics effects. Both ray tracing and physical optics engines are implemented, with an easy switching between the two via an user-friendly interface. The gratings can be modelled with a rigorous method which is cogently combined with the model for the overall system, thus allowing for

  • a realistic calculation of the efficiencies for the different diffraction orders
  • a study of the manner in which those diffraction orders propagate and interact with the rest of the optical system
  • an analysis of the spectral resolution of the spectrometer
