Overview

The Hydrogen Light Source is a cold cathode glow discharge tube, which consists of a pair of nickel electrodes enclosed in a hard glass bulb. The tube is filled with high-purity hydrogen. When the high-pressure is applied, the characteristic spectrum of hydrogen will be emitted.

Application

Used in optical instruments such as V prism refractometer and interferometer, as a monochromatic light source, it can also be used in applications requiring hydrogen spectroscopy such as college physics teaching experiments.
