20110073785	Radiation Collector - The invention relates to a radiation collector (10) designed to concentrate part of the radiation produced by a source on a spot (100). The collector includes a primary concave mirror (1) and a secondary convex mirror (2), each being rotationally symmetrical about an optical axis (X-X) of the collector. The primary mirror is configured to reflect the radiation collected with an angle of incidence (i) that is substantially constant between different points on said main mirror. Such a collector is particularly suitable for use with a discharge produced plasma source.	03-31-2011
