Abstract

The refraction lenses as well as the diffraction optical elements can be used in a projector with a lighting system, which has a light source and optical element for imaging the light field that produced by the light source on a light valve. In a version is a Fresnel lens integrated in its surface a cine-recording-lens form. This lens can be produced by die-casting in a single step.
