Gauge block calibration by interferometry

Popis výsledku v původním jazyce

Absolute length calibration of gauge blocks traceable to the definition of meter is an important task of the nationalrnmetrology institutes responsible for providing reliable length artifacts for industrial use. The length of a gaugernblock (henceforth, represented as GB) is defined in ISO 3650 as the distance between its one measuring face andrnthe surface of an auxiliary platen on which the other measuring face has been wrung. Accordingly, in centralrnlength calibration of K-grade GBs using interferometry, it is required that they be wrung onto an auxiliary platenrnwhose characteristics are the same as the measuring face of the GBs. According to this definition, the length of arnGB consists of its mechanical length between two faces and the wringing film thickness. This definition is practicalrnand reasonable in many cases because GBs are used as length standards with wringing. Also this calibrationrnmethod has the advantage that the thickness of the wringing film is propagated appropriately when lower gradernGBs are calibrated by comparison to higher grade GBs via a mechanical comparator. In terms of this paper isrnbriefly described interferometry method of gauge blocks calibration. The paper was written in conjunction withrnCzech Metrology Institute. The issue was addressed in the project TACR - TA03010663.
