Beschreibung
Zusammenfassung:	An optical system including a light guide and a turning film that includes a first major surface, where the first major surface is substantially smooth and a second major surface including a plurality of asymmetric microstructures each respective asymmetric microstructure including a first side, where the first side is substantially planar, and a second side including a first surface segment defining a substantially planar surface and a second surface segment defining a non-planar surface. Un système optique comprend un guide de lumière et un film tournant qui comprend une première surface principale, la première surface principale étant sensiblement lisse et une seconde surface principale comprenant une pluralité de microstructures asymétriques, chaque microstructure asymétrique respective comprenant un premier côté, le premier côté étant sensiblement plan, et un second côté comprenant un premier segment de surface définissant une surface sensiblement plane et un second segment de surface définissant une surface non plane.
