  • To assess & illustrate the key paraxial or Gaussian beam parameters for an imaging system
  • [paraxial mode] Select key conjugate, field & aperture parameters from comprehensive lists
  • [Gaussian mode] Select key conjugate & beam parameters from comprehensive lists 
  • See list of resultant values defining the system
  • See graphical display of paraxial or Gaussian beam layout
