LLC-9 Sodium-Tungsten Lamp

LLC-9 Sodium-Tungsten Lamp


  • 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.


Sodium Lamp20 W
Tungsten Lamp12 V/30 W, brightness variable
