    摘要: A method of calibrating an interferometer system and a multilayer thin film used for calibrating the interferometer system. The method including measuring the step height of a gold step with the interferometer system, the multilayer thin film comprising a gold layer that defines the gold step. The multilayer thin film having an optical flat, a first layer on the surface of the optical flat, a second layer on the first layer, a test layer on a part of the second layer, and a gold layer on the test layer and on a part of the second layer uncovered by the test layer. The test layer having a test layer step, and the gold layer having a gold step over the test layer step. Also, a reference standard and a method of making the reference standard for a thin film sample with one or more component thin film layers, the reference standard having a gold layer over the surface of the thin film sample.
