All calculations are first-order calculations. - For lens applications, it is assumed that lenses are aberration-free and that a strictly ray optics calculation can be used to solve the problem. This approximation is sufficient for most general optics applications. - For pinhole selection and single-mode fiber coupling applications, Gaussian ray optics equations are used. - Calculations have no correction for diffraction, aberration, or Gaussian beam optics. - Input or output angles greater than 100 mrad (~6°) may give results with errors of 10% or greater. |
