VirtualLab Fusion and its fast physical optics concept provide a platform for the analysis of complex optical systems, like monochromators, yielding fast results that include a rigorous method for the gratings which is logically included in the model for the overall system. This allows 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 possible overlap among said diffraction orders

Both ray and physical optics simulations are possible, with a user-friendly interface which permits easy switching between the two.
