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 Lamp||20 W|
|Tungsten Lamp||12 V/30 W, brightness variable|
