The apparatus (1) comprises an optical deflection element (56) provided with a wedge shaped dichroic mirror (62). The dichroic mirror contains the front and rear dichroic surfaces (63,64) which are arranged at an intermediate angle with respect to each other. Two laser beams (54,55) of different wavelengths are reflected at any one of the mirror surfaces so that the dichroic mirror ensures a spatial separation between the beam focal points (65) and emission beam bundles (59,60) triggered by laser beams. An independent claim is included for method for operating laser scanner apparatus. |
