Abstract
A vortex stabilized argon arc lamp has been developed for use as the radiant source in a new arc image furnace. 17 kW of radiant energy has been obtained from the lamp and the double ellipsoidal mirror system produces an image plane energy distribution that is Gaussian and approximately 100 mm2 in area. Flux redistributors are used to average out variations in irradiance over areas from 102 to 104 mm2. The spectral distribution of radiant energy is predominantly in the ultraviolet and near infrared wavebands with a relatively low efficiency in the visible region.
