Low Cost Optical Modeling Software by Junonia Photonics
Program FOCUS
Program FOCUS calculates the electric and magnetic fields in the vicinity of the astigmatic lens focus after the technique of Richards and Wolf (this is not a lens design program). Input and output is via text on screen, files on disk, and presentation quality graphics. The incident light may have linear, circular, elliptical, radial, or azimuthal polarization and may illuminate the lens uniformly or with a Gaussian intensity profile. The focused fields algorithm is described in more detail in Fundamental Optical Models which can be purchased at Amazon, Barnes & Noble, or Routledge.

Examples:*
Contour plots of Ex, Ey, and Ez field amplitudes (shown below) 0.2 microns behind the focal plane for incident light polarized along the x-axis.
Radial and longitudinal electric field in the focal plane for incident radial polarization.
FWHM focused spot diameter as a function of numerical aperture.
*Note: all plots are generated using commercial graphics software from the text data output of the program though presentation quality graphics on the screen are also generated by the program.
