"A flexible endoscope repair has a shaft, typically with a remote-controlled tip. In a narrower sense, it refers to pure optical-fibre endoscopes. Sometimes the term "fiberscope" is also used to distinguish it from videoscopes having an integrated micro-camera."

"How does a flexible endoscope work?

Optically:
The object is projected by an objective lens onto a thin bundle of glass fibres (each fibre diameter typically ranging from 4 µm to 18 µm and the number of fibres from approx. 3,000 to over 20,000). This "image bundle" optically transfers the image to the handle of the flexible endoscope where it is enlarged and made visible by an eyepiece lens.

Mechanically:
Flexible endoscopes consist of a movable tip, a flexible shaft and a handle. The tip including an objective lens and a sensor is controlled from the handle by means of Bowden wires in 2 or 4 directions depending on the design.

Illumination:
In flexible endoscopes, light is usually transferred from an external light source via separate glass fibre bundles to the tip, where it emerges."
