| Abstract: | Electrodeless discharge lamps, (EDL) operated with an “A” antenna are shown to be extremely temperature sensitive. Changes of up to 103 × in spectral radiant output may be produced by a 130 °K change in operating temperature. A simple device for controlling EDL temperature is described. Lamp stability and reproducibility for Hg, Cd, T1, Zn, Cu and Fe EDL are found to be greatly improved by temperature control, and lamp operation is greatly simplified. |
