Fiber optic reading magnifiers

Abstract

A reading magnifier formed by a bundle of juxtaposed longitudinally tapered optical fibers having a viewing end and a flat base end. The flat base end is cut at a bias across the bundle of optical fibers such that a line normal to the flat base end forms an acute angle with the direction of orientation of the optical fibers. The viewing end of the bundle may also be cut at an angle relative to the optical fibers. The reading magnifier provides a cone of light admittance that is skewed at an angle relative to a cylinder normal to the flat base end. The tilted admittance cone may also be achieved by bending the bottom portion of a bundle of tapered continuous optical fibers.
