ABSTRACT:
A submersible lens fiberoptic assembly for PDT treatment includes an optical fiber, a fiber jacket, a ball lens made of zirconia and a housing. This fiberoptic assembly is simple and inexpensive to manufacture, and has a high quality of output light beam. A submersible lens fiberoptic assembly for PDT treatments is also disclosed which uses a hemisphere ball lens for treatment of areas inaccessible to a normal "forward looking" lens.
