Abstract
An optical device for creating an illumination window includes radiation sources and an optical element. The optical element is arranged to create a substantially collimated radiation beam from radiation generated by the radiation sources, in which the radiation generated by the respective sources is substantially unmixed. The optical device further includes a first lens plate having first sub-lenses, in which each first sub-lens projects a part of the radiation beam at an illumination window, such that the projections of each first sub-lens at least partially overlap.
