Abstract
Abstract A fiber optics light device particularly adapted for use in illuminating an object in conjunction with an optical comparitor. The device, which transmits light to the object from a separate light source, has a generally U-shaped housing having a first pair of flexible conduits, each one of the pair connected at one end and laterally extending in the same direction from each one of the arms of the housing. A second pair of flexible conduits is connected at one end and laterally extend from the cross-member of the housing. Optical fibers extend between the distal ends of the corresponding first and second pair of conduits and through the corresponding housing arms transmitting light therethrough. The distal ends of the first conduits emit light against the object and are adjustably positionable for that purpose.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
172 words
A fiber optics light device for illuminating from a separate light source an object for viewing on a viewing screen of an optical comparitor comprising: a generally U-shaped hollow housing including a cover, bottom wall, and side walls forming a pair of spaced elongated arms extending in generally parallel fashion from either end of a cross member; a first pair of flexible conduits each having a first end secured adjacent a distal end of each said arm and laterally extending in the same direction therefrom; a second pair of flexible conduits each having a first end secured to said cross member and laterally extending therefrom in an opposite direction from said arms; an optical fiber bundle extending through each said arm and having a first end fixedly secured in a distal second end of each flexible conduit of said first pair of flexible conduits; each said optical fiber bundle also having a second end fixedly secured in a distal second end of each flexible conduit of said second pair of flexible conduits.
Claim 2
Dependent Claim
