Abstract
Emission characteristics of hydrogen taken from the hydrogen discharge lamp have been studied using an optical multichannel analyzer (OMA) system. Experimentally, a hydrogen discharge lamp was connected to high voltage power supply to induce a hydrogen discharge plasma. The atomic emission spectrum of hydrogen was then obtained from the discharge lamp via an optical fiber connected to the OMA system. Some atomic emission lines of hydrogen were clearly observed with high emission intensity and low background emission. The atomic lines of H include neutral hydrogen at the wavelengths of 434.0 nm, 486.1 nm, 656.3 nm, which represent to H gamma, H beta, and H alpha, respectively.
