Abstract

It is generally assumed that when a plane wave enters an afocal system, the wave comes out plane from the system. For instruments, like high-precision interferometers using afocal combinations, the wavefront after the second lens has opposite curvature to that which would be produced by Fresnel diffraction, if only a stop is placed at the appropiate place near the first lens.
