Abstract
Heat and light generating, fiber optic, cylindrical diffusers are structured to operate more efficiently and with increased uniformity by the inclusion of rings of prescribed indicies of refraction about the unclad distal end portion of the diffuser. Such a diffuser also includes a conical distal tip. A sealed Teflon (TM) sleeve containing diffusing material in place over the entire length of the diffuser also improves the uniformity of heat distribution.
