Abstract: Photodynamic therapy apparatus providing improved light distribution with an end fitting for use with clad optical fibers, which apparatus cooperates with an unclad stripped terminal end of the optical fiber that is inwardly tapered towards its end such that light scattering media disposed between a glass tube surrounding at least the tapered portion of the optical fiber provides improved and predictable light distribution, the media being suitably cured to a rigid relationship thereby to continuously provide improved light distribution.
