ABSTRACT:
A hollowed frusto-conical member has its base mounted adjacent the output of a laser. The apex portion extends outwardly from the laser output. The design of the member causes laser light to reflect many times as it travels from the base at a large aperture of the member down to the apex or focal point. The member may be made from light absorbing plastic material which absorbs most of the laser light and reflects only an infinitesimal portion.
