Simple, diffusive optical fiber end light distributors for photodynamic therapy were manufactured and analyzed. The scattering properties were experimentally studied with respect to various design parameters. Computer simulations confirmed the measured parameter dependence, displaying the strength of the model. The best manufactured fiber end produced an almost uniform irradiance at a radial distance of one-third of the fiber end length.
