Abstract: A supercontinuum light source ( 1000) comprising an intermediate supercontinuum light source (100) and a single mode coupling unit (300), an optical measurement system comprising such light source, as well as a method of measuring are described. The supercontinuum light source comprises a pulse frequency multiplier (103) to increase the repetition rate and the single mode coupling unit is arranged to dampen and shape the spectrum from the intermediate supercontinuum light source to allow measurements with a reduced noise floor.

Abstract: A depolarizing homogenizer comprises one or more lens let arrays, for providing a plurality of beamlets associated with different respective parts of a received beam. The depolarizing homogenizer comprises a depolarizer comprising different areas which affect polarization differently, the depolarizer being positioned to cause alteration of the polarization characteristics of at least some of said plurality of beamlets. A lens is arranged to at least partially overlap the said beamlets having said altered polarization characteristics.
