<p>A light delivery system, generally indicated at (10), comprises a frusto cone (11) which defines a cavity (12) having an anti-reflective coating (13). An optical head (14) can be mounted at the upper or inlet end (15) of the body (11). The optical head is connected to a light source, such as the laser (16) by a fibre optic (17). The cone (11) defines an outlet (16) for light emanating from the head (14).</p> |
