Description

ABSTRACT:
A lens configuration integral with the output window of an enclosure at least partly surrounding a source of a beam is provided. In one embodiment, the beam is an anomorphic diverging beam, such as that produced by a diode laser, having differing angles of divergence along parallel and perpendicular axes, and the at least one lens is configured to at least partly equalize the angles of divergence along the perpendicular and parallel axes.
