a tubular endoscopic sheath dimensioned to be accommodated in a bodily vessel or cavity;
an endoscopic tip located at a distal end of said sheath and including:
a ring lens configured as a unitary piece having a proximal end and a distal end, a reflecting surface at the proximal end and an emission surface at the distal end, and a longitudinal axis running from the proximal end to the distal end,
wherein the proximal end faces the sheath;
a support post extending longitudinally through the ring lens;
a plurality of light-emitting diode (LED) sources carried on said support post and configured to emit light radially with respect to the longitudinal axis into the ring lens towards the reflecting surface; and

to be adjacent to the emission surface,
to be substantially transverse to the longitudinal axis, and
to face an ambient medium.
