An optical beam transformation system has a sequence of optical elements
arranged along an optical axis of the optical beam transformation system
and designed for transforming an entrance light distribution striking an
entrance surface of the optical beam transformation system into an exit
light distribution emerging from an exit surface of the optical beam
transformation system by radial redistribution of light intensity. The
optical elements include a transformation element causing a radial
redistribution of light intensity and having a transformation surface
inclined to the optical axis and causing a polarization-selective
reflection of a light distribution incident on the transformation surface
according to an efficiency symmetry characteristic for the transformation
surface. The optical elements further include an optical compensation
element effecting a spatially dependent compensation of transmission
inhomogeneties caused by the polarization-selective reflection at the
transformation surface according to a compensation symmetry adapted to
the efficiency symmetry of the transformation surface.
