Abstract
A light applicator (27) for medical applications is proposed whose diffusor (1) comprises diffusion regions (7, 8, 9) with paraboloidal boundary surfaces (11, 12) This configuration of the diffusor (1) permits a particularly good homogenization of the distribution of light along the longitudinal axis of the diffuser (1).
Claims23
A light applicator with a diffusor which is attachable to a light guide and in which different diffusion regions with different scattering parameters follow successively along an optical axis of the light guide prelongated into the diffusor and in which the diffusion regions will overlap with respect to a line-of-sight aligned at a right angle to the optical axis of the light guide, wherein a boundary surface between adjacent diffusion regions has the shape of a laminar flow profile and wherein the diffusion regions are produced using silicone as a curable, liquid diffusion medium.
