Abstract

The position of the most focused point of a diffracted Gaussian beam through a finite aperture lens is investigated experimentally and numerically. It depends on the definition of the point, but it will be of most practical interest to define the point as the position where the maximum energy is received by a finite aperture detector. In considering the problem, we also discuss the effect of the curvature of the equiphase surface of the incident beam on the diffraction field.
