1. A system, comprising:
an endoscope imager (5) having a distal end and a direct imaging axis to an operating field during open surgery; and
an illumination apparatus (1) for illuminating the operating field during open surgery with radiation to cause fluorescence,
the illumination apparatus (1) comprising
a main body (2) having an extension defining an opening (3) configured to release the radiation (18), wherein the illumination apparatus (1) further comprises
attachment means (4) for attaching the main body (2) sideways to the endoscope imager (5) such that the extension of the main body extends beyond the distal end of the endoscope imager (5) and the radiation is released from the opening (3) along an optical axis that is laterally spaced from and inclined relative to the direct imaging axis of the endoscope imager (5), wherein the endoscopic imager (5) comprises a coupler (8) which allows the endoscopic imager (5) to be connected to an endoscope (21), and further wherein the coupler (8) comprises a focusing ring (24) which allows adjusting of focus of images taken by the endoscopic imager (5).
