Abstract

A plano-convex absorption glass lens proposed earlier by Ih [ Appl. Opt. 11, 694 ( 1972)] for transforming a Gaussian intensity beam into a uniform collimated beam was analyzed theoretically on the basis of the actual paths of off-axis light rays through the lens. An analysis provided by Ih did not take into account the actual light paths. The present analysis shows that a simple spherical convex curvature results in a transmitted intensity varying less than 3% for an f/15 lens. The analysis was applied to the geometry of a lens constructed by Ih, and the corresponding theoretical maximum intensity variation is in agreement with intensity measurements reported by him.
