Paper Abstract

The influence of gauge block preparation on their optical reflection properties is investigated. Results of length calibration experiments by optical interferometry performed on 9 steel gauge blocks having a wide range of surface roughness characteristics and pre-treatment are described. These data demonstrate that different conventional cleaning procedures and the use of appropriate wringing fluids have negligible effect on the reflection properties of the measurement surfaces of gauge blocks and platens.
