Light diffusing tip

A light diffusing tip comprising:

• a housing;
• and
• a monolithic light scattering medium disposed within the housing and comprising:
• a first scattering region comprising a first scattering material;
• and
• a second scattering region comprising a second scattering material, said second scattering region contacting at least a portion of the first scattering region over a substantial portion of the length of the housing;
• wherein said first and second scattering materials comprise particles suspended in a light transmissive material, the concentration of said particles in at least one of the scattering regions varying along at least one axis of the housing.

A method of forming an applicator, the method comprising:

• inserting a first scattering material into a first end of a housing to form a first scattering region, said first scattering material comprising particles suspended in a medium;
• inserting a second scattering material into the housing so as to contact a portion of the first scattering region over a substantial portion of the length of the housing to form a second scattering region, said second scattering material comprising particles suspended in a medium;
• mechanically distributing particles of said first and second scattering materials such that the concentration of said particles varies along at least one axis of the housing;
• and
• curing the first scattering material and the second scattering material to form a monolithic scattering medium.
