A light diffusing tip (23) is provided. The light diffusing tip (23) comprises a housing (28) and a monolithic light scattering medium disposed within the housing. The monolithic light scattering medium comprises a first scattering region (30) at a first position, the scattering region having a first scattering property and a second scattering region (31) at a second position, the second scattering region having a second scattering property different from the first scattering property, wherein the first scattering region (30) and the second scattering region (31) are coextensive along a substantial portion of a length of the housing (28). A light diffusing applicator also is provided. The light diffusing applicator comprises at least one optical waveguide (22), a first termination coupled to a first end of the at least one optical waveguide (22), the first termination to couple to a light source and a light diffusing tip coupled to a second end of the at least one optical waveguide (22).
