The working standard glass scale is used as an optical component for measuring and calibrating in length measuring tools such as length measuring instrument, length measuring machine, universal tool microscope and universal measuring machine. In the coordinate boring machine, coordinate grinder and other precision machine tools as a positioning element standard glass scale for measuring or positioning, and reading microscope, optical reading head or photoelectric microscope, etc. The ruler film used for tool microscope faces down and is engraved on the back of the ruler.
Basis of production and testing regulations: JJG73-2005 (verification regulations for standard glass scale)
