Abstract

The disclosure is an optical instrument which produces a concentrated beam of light by reducing the size of an incipient beam. An annular incipient solar beam is reflected inward to a concave conical lens which refracts the beam out of the lens in a direction parallel to the incipient beam. The concentrated beam is composed of parallel rays of coherent light similar to the laser beam.
