Abstract
Apparatus (20) for aiming and projecting laser radiation emitted from an output-face (56) at an output-end (52) of an optical-fiber transmitter (54), includes a target (26) surrounding the output-end of the optical-fiber transmitter and held in a fixed relationship therewith. One or more light sources (46) illuminate the target with visible light such that the target directs at least a portion of the visible light in the emission direction of the laser radiation whereby when the optical-fiber transmitter is directed toward a surface, the visible light directed by the target indicates an incidence region of the laser radiation on the surface. The apparatus optionally includes an optical system (27) arranged to project a visible image (72) of the target and an image (74) of the output-face of the optical fiber transmitter. The degree of focus of the visible target-image on the surface corresponds to the degree of focus of the laser radiation on the surface.
