摘要：
A system (100) includes a long cannula (101), an optical fiber (108), and a multi-spot generator (102). The optical fiber (108) can carry a laser beam to a distal end of the long cannula (101). The multi-spot generator (102) is located within a short cannula (103) at the distal end. The short cannula (103) is disposed within the long cannula (101). The multi-spot generator (103) comprises a faceted optical element (104) and a ball lens (106). The faceted optical element (104) can be formed directly onto or separately from the ball lens (106). The ball lens (106) can be spherical or hemispherical. The ball lens (106) is press-fit in the short cannula (103).
