ABSTRACT:
The present invention provides an improved fiber optic holding fixture for an optical interferometer, which can be used with a connector ferrule or a combination of an optical fiber end surrounded by a connector ferrule. The fiber optic holding fixture comprises a holding plate suitable for use in an optical interferometer, with a holding means for holding a prepared end of an optical fiber connection in a precision, repeatable orientation, with reference to a reference surface. The holding means comprises a vee-shaped groove in the holding plate which provides contact on two points of the circumference of a connector ferrule, as is known to the art. The improvement comprises a clamping means integrally formed within the holding plate which cooperates with the holding means. In addition, an operating means is provided which permits the selective application of force by the clamping means against a third point on the circumference of the connector ferrule held in position within the vee-shaped groove of the holding means by the clamping means. A method for the use of the device is also provided.
