Abstract
A spatial beam shaper structure and a corresponding optical system are provided. The spatial beam shaper structure comprises a light collecting surface configured for affecting light impinging thereon to provide a substantially smooth light profile of at least one optical property, the light collecting surface having a pattern in the form of multiple surface regions comprising regions of at least two different optical properties arranged in an alternating fashion, wherein an interface region between each two locally adjacent regions of the different optical properties has the at least two different optical properties, to provide substantially smooth transition of said different optical properties within the interface region.
