LLC-9 Sodium-Tungsten Lamp

Note: post holder and magnetic base not included


  • Compact design

  • Housing and power supply included

  • Two lamps in one unit


LLC-9 integrates a Sodium lamp and a Tungsten lamp in one unit. It can be used in interferometry experiments to demonstrate white light interference and observe the interference fringes of Sodium D-lines. Moreover, the wavelength separation of Sodium D-lines is a typical measurement example in interferometry experiments.
