Light emitter comprises a number of partial light sources (3a-3d) that generate partial beams (5a-5d) that are collected by collecting optics (2) and guided to the aperture of a collimator (1). The collecting optics (2) has two half-reflecting plates (12a, 12b) which each guide two equally polarized part beams (5a-5b; 5c-d) onto a polarization cube (13), where the beams, that are polarized at right angles to each other, are superimposed. |
