The Fabry-Perot interferometer (LEOI-18) is a standalone device that can be used to observe multiple-beam interference fringes and measure the wavelength separation of Sodium D-lines. When equipped with other components, this device 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).
