ABSTRACT:
The system comprises two light sources which are diametrically opposed relative to the optical axis of the system. In the axis there is provided a light-mixing mirror which has a generally sulcated face having grooves therein of triangular cross-section and raised portions of triangular cross-section separating the grooves. Light coming from the two light sources slightly diverges when it impinges the sulcated face of the mirror and is deflected into the direction of the optical axis thereby being intensively mixed.
