ABSOLUTE SPECTRAL DISTRIBUTION MEASUREMENTS OF XENON HIGH-PRESSURE DISCHARGES.
Abstract
The report covers the work conducted to obtain in absolute units the spectral distribution of a 10-kilowatt, xenon, compact arc lamp. The wavelength range of these measurements was selected between 2,400 and 11,000 Angstroms (A) at four different power levels: 2.6, 5, 7.5, and 10 kilowatts. The results were obtained in absolute units of radiance: watts/(steradian) (sq cm)(1 A interval). The report concludes that: (1) The highest radiance was between 800 and 900 millimicrons. (2) The blackbody temperature producing the same radiance at 0.8232 micron as on the xenon spectrum was 9775K. (3) The connection between total radiated energy from 0.2 micron and 1.1 microns and lamp power is, within the measured range, almost linear. (4) With increasing lamp power, increased line broadening and continuum appear as is to be expected. (Author)
