Fiber optic taper is a hard fiber optic element made of optical fibers with an varying diameter. Fiber optic taper is designed to change the scale of the transmitted image, for the concentration of light energy.

Fiber optic tapers are applied in various electron-optical systems, in medical technique. In some application fiber optic taper provides compact, effective connection of the luminescent screen and photodetector array.
