Point Diffraction Interferometer

Product Overview

The Point Diffraction Interferometer (PDI) is a high-precision optical testing instrument used for wavefront analysis, high-resolution metrology, and advanced optical system evaluation. Unlike traditional interferometers, the PDI relies on diffraction from a small reference aperture to generate a highly accurate wavefront, making it ideal for measuring aberrations, optical component quality, and laser beam characterization. This system is widely used in scientific research, aerospace optics, and precision manufacturing applications.
