Abstract

The arrangement has a light source for producing at least one primary beam and an optical beam divider (24) with reflective surfaces dividing the main beam into at least two mutually perpendicular sub-beams. The source has two semiconducting lasers (22,23) with emitting surfaces with longitudinal and transverse length ratios of about 2.5:1 to about 4:1, whereby the primary beams from the two lasers are superimposed.
