<p>The laser beam therapeutic machine has an adjustable arm (3) which pivots about a point (29) at the top of a fixed arm. The latter houses the laser (2), and the adjustable arm has an entry mirror (4) at the pivot point. At the other end is a second mirror (6) mounted at another pivot point (13). An objective lens (7) is at the outlet (33) following this mirror (6). Between the two mirrors is a light guide. An inner port (28) of the adjustable arm slides telescopically inside the port (27) which carries the entry mirror at the top end. The reflected laser beam travels along the central axis of the telescopic arm.</p> |
