• a light refracting element configured to bend light received through the window toward a light gathering element associated with the endoscope;
• or
• retaining functionality configured to allow the light refracting element to be one or both of:
• placed into the obturator to bend the light toward the light gathering element or attached to the obturator to bend the light toward the light gathering element.
