Abstract
An endoscopic system for internal inspection of an object includes an endoscope extending along a longitudinal axis between a distal end to be inserted into the object and a proximal end and an illumination assembly attached to the proximal end of the endoscope. The illumination assembly includes a solid-state light source. The endoscopic system also includes an optical system positioned distally from the solid-state light source to receive and convey light to the distal end.
Claims24
An endoscopic system for internal inspection of an object comprising:
- an endoscope extending along a longitudinal axis between a distal end to be inserted into the object and a proximal end;
