    Abstract: A concave optical fiber ferrule holding plate for polishing an end face of an optical fiber is disclosed. The holding plate may be used alone for hand polishing or be provided as a component of an optical fiber polishing machine. The circular holding plate comprises a concave interior with one or more concentric wear rings disposed radially inwardly on said interior from the outer periphery of the holding plate to a point surrounding the optical fiber ferrule located in the center. The holding plate contacts a polishing material only at the peripheral wear ring thereby reducing contamination from the material of the holding plate which reduces contamination of the end face of the fiber during polishing. The degree of deterioration of the wear rings can be easily observed to determine when the ferrule holding plate must be replaced.

The apparatus includes a framework, a holding mechanism carried by the framework for holding the prosthesis in a position which permits micro-etching, and a flexible hood, for example, a disposable plastic bag, which has an open end sized to slidably receive the framework into the hood while holding the prosthesis. The open end is sealable while the framework is so received, and the hood is transparent to permit viewing of the prosthesis within the hood. The hood is sliceable with a knife edge to provide a small slit which permits the tip of a micro-etching tool to extend into the hood. Alternately, the hood may be pre-slit for the same purpose.
