-Instrument Introduction

This laser interferometer can perform classic Michelson interference, Fabry Perot interference, and Taylor Green interference experiments. The instrument design is exquisite, and the integrated structure can greatly reduce experimental adjustment time and improve experimental efficiency. At the same time, all structural components are fixed on a heavy small platform to prevent vibration from affecting the experiment. Michelson, Fabry Perot, and Taylor Green modes can be easily converted, with rich experimental content, simple operation, and accurate results, making them a good choice for conducting combined interference experiments.
