Experimental Instruments ยป Interferometer of Michelson and Fabry-Perot Model EWMG-1

Introduction

This equipment can be easily transformed between the historically important Michelson Interferometer and the high resolution Fabry-Perot Interferometer. It applies to optical experiment in physics teaching at institutions of higher learning.

Key features
  • Precise measurements with two modes of operation.
  • Easy operation and stable performance.
  • Documentation contains both theoretical and practical descriptions.
Experiment Examples
The Michelson Interferometer
