Arrangement for polarization of light

An arrangement for the polarization of light, for use in projectors, comprising:

• at least one illumination source;
• an integrator with a light entrance plane and a light exit plane which serves to homogenize the unpolarized light bundle coming from the illumination source and/or illumination sources;
• a structural component part which has an entrance opening and which is constructed so as to be reflecting in the direction of the interior of the integrator, and the intensity maximum of the light bundle propagates along an axis extending between the light entrance plane and the light exit plane;
• said structural component having surfaces formed so as to be reflecting for guiding the light bundle;
• means for polarization and reflection of partial beams of the light bundle entering the integrator;
• and
• at least two reflecting polarizers being arranged in the light exit plane of the integrator in the same angular position relative to the axis of the integrator, the polarizers having polarization directions that are rotated relative to one another, and phase plates which adapt the polarizers with non-transmitted polarization directions to the polarizers with transmitted polarization directions being provided outside of the integrator.
