ABSTRACT:
The laser positioning device (10) as a housing (12) and a number of individual diode lasers (18) accommodated in the housing. The diode lasers can be energized to produce individual laser beams. Beam fanning means, preferably in the form of tubular lenses (28), are used to fan the laser beams to produce parallel, fanned beams (65) which are then projected from the housing (12) through a window (58). The positions of at least some of the diode lasers in the housing are adjustable by means of an endless cable and pulley mechanisms.
