Why does an endoscope contain several optical fibers?

Answer 1

Formerly, endoscope optics consisted of a series of thin converging "relay lenses", creating a succession of images in the air spaces between them. Following the innovation by Harold H Hopkins, the thin lenses in air were replaced by thin air lenses in glass. In other words, each lens consisted of a rod, with convex polished surfaces at each end. This increased the light throughput, and avoided the metal spacer rings needed in the old design. Some endoscopes instead use bundles of fiber optics to convey the image, which renders them flexible.

Answer 2

An endoscope contains several optical fibers to transmit light from the light source to illuminate the area being examined inside the body. Additionally, other optical fibers are used to carry the image of the tissue or organ back to the eyepiece or camera attached to the endoscope for visualization. Having multiple fibers allows for better image quality and flexibility during the examination.
