Abstract
Non-uniform transmission filters are used to modify the response of an optical system. We have applied different types of annular colour filters to systems with residual chromatic aberration and an achromatic correction. These filters can shift the chromaticity at the maximum (that is out of the white zone due to the residual chromatic aberration) to the white zone. They can also modify the illuminance distributions in different ways, producing effects like hyperresolution, apodization and variation of the depth of focus.
