Introduction
The Fabry-Perot interferometer (LEOI-18) is a standalone instrument that can be used to observe multiple-beam interference and measure the wavelength separation of Sodium D-lines. When equipped with other components, this setup can be used to conduct other experiments such as to observe the spectral shift of a Mercury isotope or the splitting of spectral lines of atoms in a magnetic field (the Zeeman effect).
The instruction manual contains comprehensive materials including experimental configurations, principles and step-by-step instructions. Please click Experiment Contents to find more information about this apparatus.
