Assembly for projecting an image onto a projection surface

Apparatus for projecting a picture on a projection screen, comprising a light source for emitting light, wherein the light source can generate a luminous area, a reflective light modulator that can be illuminated with light emanating from the luminous area and that can modulate the light for the purpose of generating a picture, a projection optics which is arranged following the light modulator and can be illuminated with the modulated light for projecting the picture on the projection screen, the apparatus further comprising an optics system arranged in front of the light modulator, wherein the optics system images light received from the luminous area on the light modulator, and images the light modulated by the light modulator in an intermediate image level that is located in front of the projection optics for generating an intermediate image in the intermediate image level, wherein the projection optics can project that intermediate image on the projection screen and wherein the optics system comprises catadioptric optics.
