Spectrum Tube

Spectrum Tube

Spectrum tubes are glass tubes filled with a gas, usually that of an element or small molecule.

When a spectrum tube is placed in a spectrum tube power supply and the power supply is turned on, an electrical discharge is passed through the tube, causing electrons in the gas to be excited.
