Abstract : A miniaturized ellipsometric testing device comprising first means for precisely impinging a prescribed beam of light upon a surface to be tested and second means for capturing the reflected impinged beam only within prescribed limits. The value of the reflected impinged beam, which is transmissible to a detector, is used in determination of the validity of the surface tested; the miniaturized device is couplable to a laser light source and said detector by means of respective fiber optic cables.
