Abstract

In this paper we investigate the dependence between target-distribution contrast and decrease in optical performance of the free-form optics due to misalignment along the optical axis. It is shown that by reducing the target-contrast, the optical performance of the resulting illuminance distribution can be increased at different target distances and for different light source positions.
