A method and system for condensing and collecting electromagnetic radiation comprised generally of a radiation source, a reflector and a target is disclosed. The reflector has a reflecting surface for reflecting the radiation from the source which is in the shape of a cut out portion of an ellipsoid. The reflector surface has a substantially ellipsoidal curvature which is concave relative to both the target and the source, and which has a major axis, a minor axis, and a first and second focal points. The system of the present invention redirects radiation emitted from the source, located near the first focal point of the ellipsoid, to produce a magnified image of the source at the target, located near the second focal point of the ellipsoid. To acheive this spot size magnification, the ellipsoidal reflector surface comprises a portion of an ellipsoid which lies between the major and minor axes of the ellipsoid. The method disclosed comprises producing a magnified image of the source at the target by redirecting magnification emitted from a source with reflector having a concave surface shaped substantially of an ellipsoid.
