The present invention provides devices, methods of manufacture, methods of use and kits related to transmitting and diffusing light for delivery to a target site. Techniques are provided which allow accurate control of the illumination profile with a diffuser tip design which is easily produceable, relatively inexpensive and provides countless variations to obtain desired illumination profiles. This is achieved with the use of at least one scattering region having a conical shape. The number of conical scattering regions, the dimensions of such region(s), and the scattering properties of the scattering materials may be selected individually and/or collectively to selectively control the resulting illumination profile. In addition, the conical features allow for other beneficial design features, such as a smaller cross-sectional diameter than is typically achievable with other techniques. The resulting light transmission and diffusion apparatus is operable with a high efficiency, highly predictable illumination profile and ease of use.
