ABSTRACT:
Device for attachment to gauging instruments such as optical measuring apparatus, which measure dimensional parameters of articles by scanning the surface or main profile of the article with a light beam as from a laser, the device employing a leaf spring assembly for bearing against and conforming to a portion of the surface of the article; the leaf spring assembly thereby forming a substitute profile over the main profile of the article or of a transparent article, and suppressing any surface anomalies projecting from the article surface, thus providing a reference surface which may be measured by such gauging instruments as representative of the dimensional parameter of the main profile of the article.
