ABSTRACT:
A light-beam-operated heating apparatus for concentrating light into a focussed line of light for soldering or the like. The apparatus forms multiple beams from a single source; each beam having a non-uniform intensity along a first axis which is in a plane perpendicular to the optical axis of the apparatus. The beam is concentrated by a concentrator lens along a second axis in the same plane as and perpendicular to said first axis, thereby forming a line of light which has non-uniform intensity along the line. A diffuser is positioned to intercept the beam and defuse the light beam along said first axis, thereby reducing the non-uniformity of the light intensity.
