Abstract : This report describes a hand-holdable apparatus for testing, and a method of testing, a light-reflective surface for contamination. The apparatus and the method are based upon a novel off null ellipsometry technique by the use of which contamination of the surface is ascertained, if the intensity of light reflected by the surface being tested exceeds a predetermined threshold of intensity.
