3 Overview

The plane isometric interferometer is a standard measuring instrument used for the transmission of flat quantity, mainly used for large size verification. The flatness of flat crystals, long flat crystals of various sizes, and standard flat feet. The working principle of the instrument is shown in Figure 1.
