CastIronDave · Accepted Answer

Optical fibre bundle end. When you look through a fiber optic bundle endoscope, you're essentially seeing through thousands of tiny glass straws, and the image quality depends on whether those straws are arranged in an organized grid or jumbled randomly—organized bundles create sharp medical images, while scrambled ones produce blurry abstract patterns that look almost like impressionist paintings. Incredibly, this difference in arrangement is so critical that it's one of the main reasons modern endoscopes cost tens of thousands of dollars more than older models.
