Absolute Spectral Distribution of Cesium and Rubidium Arc Lamps.

摘要

Spectral radiance data in absolute units was obtained from 2-KW cesium and rubidium arc lamps operated at various power levels and vapor pressures to determine optimum operating conditions for maximum visible and near infrared output. The report concludes that rubidium has a favorable distribution at high vapor pressures for use with a pink filter (low density infrared filter) and an S-25detector in infrared mode,and cesium has a favorable distribution at intermediate pressures for use with a filter with a higher degree of visual security and an S-1detector. more development of the lamp is needed to increase radiance and total efficiency.
