Abstract
Diffraction fields in the focal space of some lens is investigated by using
ray tracing and Stratton-Chu formulas. Two formulas are used. One is surfa
ce integration formula, and for another a line integration is added. Compar
ison of two calculation results is given. It is shown that for hyperbolic l
ens two calculations results are same and for extended hemi-ellipsoidal len
s there are a lilt difference between them.
