It is presented an optical component (5) a first side (30) and a refractive opposite side (14). The refractive side (14) presents a refractive surface (13) and has radially extending refractive structures (6) for refracting light mainly in the azimuth direction (27) of an inciding light beam. The optical component (5) can be used as an exit window in a luminaire (1) having at least one light source (4), whereby light inhomogeneity may be reduced. |
