Abstract: The invention relates to an optical arrangement comprising at least two optical elements, such as Fresnel lenses or linear prism sheets arranged with their structured surfaces pointing toward one another, and to the use thereof for various projectors and displays. The solution according to the invention seeks to reduce light losses and allows a large intercept distance on one side. This object is achieved by the active edges of the two optical elements that are designed and oriented with respect to one another in such a way that light enters or emerges from the active edges of one of the two optical elements at least in a virtually orthogonal manner.
