Fiber-optics faceplate

A fiber-optic plate (FOP) is a hard plane-parallel or flat-concave element in which fibers are fused together to form a vacuum-tight glass plate.

FOPs are used to transmit images in electro-optical converters, which are used in instruments for scientific research, television technology.
