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/5 lens. The analysis was… CONTINUE READING
