ABSTRACT:
A focusing device for concentrating radiation, such as sunlight, and producing a prescribed distribution of energy over a target surface. The principles of the device have both photovoltaic and photothermal applications, and can be embodied in either a lens or a mirror, having a plurality of discrete focusing surfaces for redirecting radiation onto a target surface. The angle for each of the respective focusing surfaces, relative to the direction of the radiation being received, is selected to redirect an increment of such radiation to a unique portion of the target surface, whereby a superposition of the radiation increments redirected by all of the focusing surfaces produces the prescribed distribution of energy on the target. In one embodiment, a plurality of focusing segments is provided each having a plurality of the focusing surfaces for irradiating the target surface with a prescribed energy distribution. Apparatus is provided for selectively masking predetermined ones of the focusing segments for controllably adjusting the magnitude of light energy concentrated upon the target surface in a plurality of known and discrete steps.
