FIELD: optics. ^ SUBSTANCE: proposed method aims at producing light homogenisation device comprising at least one substrate (1) that features at least one optically functional surface with large amount of lens elements (2) that, in their turn, feature systematic surface irregularities. At the first stage aforesaid lens elements (2) are formed in at least one optically functional surface of at least one substrate (1). At the second stage at least one substrate (1) is divided into at least two parts (3, 4). Then at least two aforesaid parts of substrate (1) are jointed together again, provided there is a different orientation of at least one of aforesaid parts (4). The said different orientation of one of at least two parts allows preventing addition of light deflections caused by aforesaid systematic surface irregularities after light passage through separate lens elements. ^ EFFECT: higher efficiency of light homogenisation. ^ 16 cl, 8 dwg |
