Abstract
An endoscope that has an integrated light source and camera mounted at the distal end of the endoscope. The light source is a class of LED devices constructed of high-efficiency LEDs that emit narrow-band blue light coupled with phosphors, which cause a nearly natural “white” light to be emitted. The LEDs are coupled to a waveguide for transmission of the light to the distal end of the endoscope.
Claims13
An endoscope comprising:
- a) a tube with a proximal end and a distal end and defining a longitudinal axis, the distal end comprising a light guide defining a lumen, the light guide comprising:
- i) a collimator segment;
- and
- a transmission segment distal to the collimator segment and having a smaller cross section than the collimator segment;
- b) a video camera positioned within the lumen of the light guide;
- and
- c) a white light source positioned at the distal end proximal to the video camera and optically coupled to the collimator segment of the light guide.
