GratingsPro!

Surface Relief Optical Grating Calculator. It calculates diffraction efficiencies vs Angle of Incidence or Wavelength or Thickness for any linear polarization and any rotation of the plane of incidence around propagation axis for 1D and 2D-dimensional surface relief gratings and 1D Volume Phase Holographic gratings. Different type of gratings can be modeled by adjusting Offsets of each later, i.e, Blazed Gratings, Triangular Gratings, etc.
