Abstract
The present invention provides devices and methods of manufacture related to transmitting light to a target site for diffusion Techniques are provided which allow accurate control of the illumination profile with a diffuser tip design which is easily producible, relatively inexpensive, and provides variations to obtain desired illumination profiles. This is achieved by using at least two light scattering mediums having a shape defined by an insert. The dimensions, light scattering properties, and number of such light scattering mediums may be selected individually or collectively to selectively control the illumination profile. In addition, the insert allows for other beneficial design features, such as a reduced heat retention, easily controlled and refined light scattering medium interfaces, and 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.
