Abstract
An optical scope includes a body and an elongated shaft. The shaft distal end holds an optical assembly including an imaging lens with a field of view of at least 90 degrees. An LED is coupled to the body and has an output numerical aperture (NA) providing a critical angle larger than the field of view. A first pair of fiber bundles have proximal ends receiving light from the LED with distal ends presented at the shaft distal face, and an NA providing a critical angle less than the field of view. A second pair of fiber bundles also receive light from the LED with distal ends having at the shaft distal face, and have an NA providing a critical angle at least as large as the field of view. The bundles are positioned around imaging lens such that they create a light having a desired intensity profile and properties.
