An optical circuit for delivering lamp radiation to the light guide of the illumination channel of a medical endoscope was developed. The proposed optical circuit splits the lamp light flux into two parts using systems consisting of a spherical mirror and a lens located opposite each other symmetrically with respect to the lamp. Next, the light fluxes are introduced through focusing cones into intermediate light guides and merged. The resulting light flux is then introduced into the light guide of the illumination channel of a medical endoscope. According to the estimates, the proposed optical system provides delivery of ~25% of xenon-lamp radiation into the light guide of the endoscope’s illumination channel.
