Abstract:
A fiberoptic block comprising a plurality of unit fibers which are bundled together such that respective axes thereof are substantially parallel to each other, both end faces of said unit fibers being respectively collected together to form input and output end faces;wherein said input end face is formed by a plurality of ridge portions arranged, each of said ridge portions having a slope inclined with respect to the axis of each of said unit fibers;wherein an angle of inclination of said slope of each of said ridge portions is an angle at which light incident on each of said unit fibers from within the air by way of said slope is prevented from being propagated through said unit fiber;wherein tops of said ridge portions are flush with a plane orthogonal to the axis of each of said unit fibers; andwherein said output end face is a surface orthogonal to the axis of each of said unit fibers.
