- Instrument Overview
This laser interferometer is capable of performing classic Michelson, Fabry-Perot, and Tiemann-Green interference experiments. The instrument features a compact, integrated design that significantly reduces experimental setup time and improves efficiency. Additionally, all structural components are mounted on a heavy-duty base plate to minimize the impact of vibrations on the experiment. The system allows for easy switching between the Michelson, Fabry-Perot, and Tiemann-Green modes. With its diverse experimental capabilities, simple operation, and accurate results, it is an excellent choice for conducting combined interferometry experiments.
