Introduction   

The Hydrogen lamp is a long glass tube filled with Hydrogen gas that is stimulated electrically. As a voltage is applied between the cathode and the anode, an electrical current will flow through the gas, and excite the electrons of the Hydrogen atoms. Hydrogen lamp can be used for wavelength calibration in the UV range as it radiates continuously in that range. By contrast, the Hydrogen lamp does not produce a continuous visible spectrum, but discrete lines. Four of these spectral lines are in the visible range. Among them, the spectral line at 656.3 nm is the brightest, which makes the lamp red to a naked eye. The rest spectral lines lie in the ultraviolet and infrared regions.
