Laser system for medical and cosmetic applications

摘要

The invention concerns a laser system (1) for medical and cosmetic applications. The laser system (1) comprises an optical delivery system (2) for guiding a laser beam (3) to a target surface (4). The optical delivery system (2) has an external optical element (5) facing toward the target surface (4). A mechanical filter in the form of a protective screen (6) is arranged at the exit side of the external optical element (5) for shielding the external optical element (5) from particles (7) ejected by the laser beam (3).
