Abstract
In an illuminating apparatus for projection purposes, in particular a film projector or television image projector by the eidophor system, four condensers are located around a source of light in a cube-shaped housing, the condensers reproducing via the use of deflecting mirrors, an image of the light source on several, spatially adjacent imaging mirror segments, which in turn reproduce the condenser images superimposed upon one another, via an output mirror, on an image aperture of the projection optics.
