Paper Abstract

Non-uniform transmission filters are used to modify the response of an optical system. Grey non-uniform filters produce important effects on the illuminance distributions both in the transverse and along the axis. Nevertheless, grey filters do not change the chromatic response significantly. So, we propose some types of annular color filters which modify the transverse and axial illuminance distributions, and they also modify the chromaticity distributions.
