Abstract
A device for generating multiple collimated light beams includes a carrier and at least two light generation units mounted on the carrier. The light generation units are configured to emit, each from an aperture, light beams at respectively different wavelengths and being arranged, with respect to axes of the light beams, substantially parallel and substantially in a common plane. A first lens is mounted on the carrier intersectingly to the axes of the light beams and has a principal plane. The light generation units have their apertures aligned along an alignment line substantially perpendicular to the axes of the light beams and the principal plane of the first lens is non-perpendicular to the axes of the light beams and is non-parallel to the alignment line.
