fiber optic sights
An optical fiber is a glass or plastic fiber designed to guide light along its length by total internal reflection. Fiber optics is the branch of applied science and engineering concerned with such optical fibers. Optical fibers are widely used in fiber-optic communication, which permits digital data transmission over longer distances and at higher data rates than electronic communication. They are also used to form sensors, and in a variety of other fiber optic sights.
The operating principle of optical fibers applies to a number of variants including multi-mode optical fiber optic sight, single-mode optical fibers, graded-index optical fibers, and step-index optical fibers. Because of the physics of the optical fiber, special methods of splicing fibers and of connecting them to other equipment are needed. A variety of methods are used to manufacture optical fibers, and the fibers are also built into different kinds of cables depending on how they will be used.
