<p>#CMT# #/CMT# The laser system (1) has radiation source (3) which is provided for emitting laser beam (5) along propagation direction (6). A focusing lens assembly (8) is arranged with respect to optical axis (12). A conical mirror (9) is formed with reflecting lateral surface (14) with respect to cone axis (15). The conical mirror is arranged behind the lens assembly in the beam path of the laser beam such that cone axis is set parallel to optical axis of lens assembly. The propagation direction of the laser beam is inclined at an angle relative to optical axis of lens assembly. #CMT#USE : #/CMT# Laser system for creating linear laser mark. #CMT#ADVANTAGE : #/CMT# The linear laser mark can be created efficiently with opening angle smaller than 360 degrees. The opening angle of the linear laser mark can be adjusted reliably. The visibility of linear laser mark can be enhanced without the need for supplementary optic element. Hence, the number of optical components can be reduced and complexity of the laser system can be avoided. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of laser system. 1 : Laser system 3 : Radiation source 5 : Laser beam 6 : Propagation direction 8 : Focusing lens assembly 9 : Conical mirror 12 : Optical axis 14 : Reflecting lateral surface 15 : Cone axis.</p> |
