Abstract
A solar concentrator assembly (102) comprises a concave mirror (108) for collecting radiation that is collimated and has uniform distribution from a source and a convex mirror (110). The concave mirror (108) is configured to reflect the radiation to the convex mirror (110) and the convex mirror (110) is configured to reflect the radiation as a concentrated collimated beam in an emission direction that is angularly offset from the source. The concave mirror (108) and convex mirror (110) each have a focal length that varies along one axis such that the radiation collected by the concave mirror (108) is transmitted from the convex mirror (110) with uniform distribution.

A solar concentrator assembly comprising:
- a concave mirror for collecting radiation that is collimated and has uniform distribution from a source;
- and
- a convex mirror;
- the concave mirror being configured to reflect said radiation to the convex mirror;
- the convex mirror being configured to reflect said radiation as a concentrated collimated beam in an emission direction that is angularly offset from the source;
- the concave mirror and the convex mirror each having a focal length that varies along one axis such that the radiation collected by the concave mirror is transmitted from the convex mirror with uniform distribution;
- and
- the solar concentrator assembly further comprising two sets of the concave mirrors and the convex mirrors arranged rotationally-symmetric and 180° about a direction of the source.
