Optica is an outstanding program for geometric ray tracing. The current
version of Optica does not handle diffraction, near-field or otherwise. It
will however plot "spot diagrams" for you, and do some modest kinds of
diffraction computations related to gratings.

If your apertures are typical, then they are circularly symmetric, and you can
compute the far field diffraction pattern using a Hankel transform. For
problems with circular symmetry, the two-dimensional Fourier transform becomes
a one-dimensional Hankel transform. In Mathematica, this transformation can be
computed numerically or analytically.

Near field work is a little more complicated because far-field
approximations are not admissible.
