The Michelson interferometer teaching device is a high-precision optical measurement instrument designed based on the Michelson interference principle, utilizing the amplitude-splitting method to generate two-beam interference. It is widely used in various fields, including optical engineering, materials science, semiconductor manufacturing, etc., for measuring parameters such as reflection, transmission, and surface topography of optical components. The goal of this experimental project is to familiarize students with the interferometer as a highly sensitive measurement instrument. Due to its extensive applications in technology and industry, this kit is designed with multiple experiments aimed at demonstrating measurement methods for different physical properties. This experiment enhances students' hands-on abilities by assembling a Michelson interferometer themselves. Using the interferometer for practical measurements helps students deepen their understanding of the fundamental principles of the Michelson interferometer while learning and mastering the principles and methods of interferometric measurement.
