The device comprises a body (3) and an optical unit (5), movable with respect to the body (3) along a translation axis (Z). The optical assembly houses the focusing lens (7) with the optical axis (A-A) of the focusing lens (7) parallel to the translation axis (Z) of the optical unit (5). The optical unit comprises a slide (11) which slides along a linear guide system parallel to the translation axis (Z). The device further comprises a magnetic actuator (23) comprising an electromagnetic stator (25) integral with the body (3) and a magnetic piston (27) constrained to the optical unit (5). The magnetic piston (27) is housed in a seat (24) formed in the electromagnetic stator (25) and movable along a motion axis (B-B) parallel to the translation axis (Z) of the optical unit (5).
A device for the movement of a focusing lens along an optical axis of the focusing lens, the device comprising:
A laser head comprising a laser source and a movement device;
A linear magnetic actuator, comprising an electromagnetic stator with a cylindrical wall, defining a cavity, in which are arranged a first electro-conductive coil and a second electro-conductive coil, wherein said electro-conductive coils surround a magnetic piston slidingly housed in the first electro-conductive coil and in the second electro-conductive coil and coaxial thereto;
