Abstract

In an endoscope infra red laser radiation is introduced into the proximal end by deflection at a mirror, and is then passed through an optical relay system that comprises lenses 7a made of crystals which pass infra red light (e.g. germanium or zinc selenide crystals). Alternatively the laser beam is prefocussed to an optimum degree and is transmitted to the distal end of the instrument via a waveguide 7. <IMAGE>
