ABSTRACT:
A diffusing tip is provided for diffusing light from a light-emitting end of an optical fiber in a radial distribution pattern relative to the axis of the tip and along a length of the tip. The tip has an inner core and an outer covering which define a light guide. The outer covering is modified on its interior surface adjacent to the core such that light transmitted down the light guide is removed from the core upon encountering a surface modification on the interior surface. The light so removed is transmitted to the outer surface along the length of the tip, where it can be used to irradiate a selected object or material. The diffusing tip preferably provides light in a substantially uniform intensity distribution for the substantially uniform irradiation of a selected object or material.
