Fiber optics welder having movable aligning mirror

Claim 1

In a system for joining two lengths of a fiber optic waveguide together, apparatus comprising: a. A base, b. A first clamping means fixedly attached to said base for holding an end of a first length of a fiber optic waveguide in a vertical orientation, c. A second clamping means for holding an end of a second length of said fiber movably mounted to said base through a three-axis micropositioner, whereby said fiber ends may be brought into vertical, colinear and abutting alignment, d. A stereoscopic microscope for viewing said fiber ends, mounted on said base, e. A pair of electrodes mounted to said base through a three-axis micropositioner whereby said electrode pair may be moved into precise alignment with the junction between said fiber ends for welding said fibers and out of the way during alignment of said fiber ends, f. A mirror mounted to said base through means permitting said mirror to be moved into and retracted out of a position alongside of the fiber ends and at a 45° angle to the optical axis of said microscope whereby two right orthogonal views of the fiber ends are provided through said microscope while said ends are aligned and the mirror may be moved out of the way during alignment of said electrodes, and g. Means for establishing an arc between said electrodes for welding said ends together.
