Scientific paper

The high-magnification regions in the object plane of an extended spherical gravitational lens are investigated by removing the two idealizations that lead to infinities: point sources and geometrical optics. The geometrical optics of an extended spherical lens is eamined, and a physical-optics calculation is performed. Simple order-of-magnitude expressions are derived for the absolute upper limits to the gravitational lens effect set by physical optics, as well as for the diffraction phenomena associated with both the 'halo' and the 'spike' singular images predicted by geometrical optics. The results obtained tend to confirm existing probability calculations and also predict interesting diffraction phenomena for sources near the singular curves.
