Radiant Flux Measurements of Ultraviolet Emitting Light Sources

G. R. Spears

Abstract

Measurements have been conducted and data have been available on radiant flux measurements of ultraviolet light sources for many years. However, there was a high degree of uncertainty in the results below 300 nanometers. The most recent NBS standard of spectral irradiance permits measurements to be conducted in the 250- to 315-nanometer region with greater confidence. This paper describes a procedure for obtaining precise measurements of spectral irradiance and spectral radiant flux in the ultraviolet region.
