Abstract
In a light delivery system comprising a lightguide coupled to an optical apparatus for delivering substantially uniform light to a predetermined plane within the apparatus, images of non-uniformities caused by imperfections at or near an outlet end of the lightguide are displaced away from the predetermined plane. The image displacement may be performed by a lens adjacent the end of the lightguide, or integral therewith, or by a suitably formed plug or end cap of a liquid lightguide.
