Abstract

For the circumferential irradiation of objects, especially of vessels, hollow organs and solid tissue, by optical radiation of high intensity which is conducted via a flexible optical fiber, the optical radiation is coupled into the optical fiber at a predetermined angle (.beta..sub.1,.beta..sub.2) to the surface normal of the end face of the optical fiber such that it leaves the distant end of the optical fiber in the form of a conical surface.
