1. An illumination system for a medical technology therapy and/or diagnosis system, comprising:
a light source;
an optical waveguide having a proximate end and a distal end, the proximal end is connectable or assignable to the light source; and
an optical element arranged at the distal end so that light from the optical waveguide is injected into the optical element, the optical element defining a longitudinal axis (L) and having a lateral surface extending around the longitudinal axis, wherein the lateral surface is at least in a section covered by a reflector layer,
wherein the reflector layer comprises a mirror layer and the optical element comprises a light-reflecting area covered by the reflector layer, the optical element further comprising a light-transmissive area that remains free of the reflector layer so that the light injected into the optical element is reflected at the light-reflecting area and is emitted from the light-transmissive area,
wherein the reflector layer exhibits a reflectance of more than 90% for at least one wavelength range.
