<p>A fiber optic, cylindrical, light diffuser (40) for medical use includes an unclad distal fiber end (45) where the exposed core end has a conical shape. The core end (45) is enclosed by a sleeve (48) which contacts the clad portion (42) of the fiber only and defines a closed chamber (51) with the distal end (45) of the fiber. The chamber (51) is filled with light diffusing material. The diffuser (40) exhibits highly uniform output light distribution and is capable of carrying relatively high power densities safely.</p> |
