Abstract
In certain embodiments, a method includes forming a ferrule from a portion of a tube. The tube is cut to yield the ferrule and a short cannula. A multi-spot generator with a faceted optical element is added to the short cannula. An optical fiber is placed into the ferrule, and the ferrule and the short cannula are assembled. In certain embodiments, a system includes a long cannula, an optical fiber, and a multi-spot generator. The optical fiber can carry a laser beam to a distal end of the long cannula. The multi-spot generator is located at the distal end and comprises a faceted optical element and a ball lens. The faceted optical element can be formed directly onto or separately from the ball lens. The ball lens can be spherical or hemispherical.
