Abstract

To serve the interests of workers in certain fields of extremely low irradiation such as is present in the air-glow and in phosphorescent, fluorescent, biochemical, and associated areas, a standard of spectral irradiance of extremely low intensity has been set up. This standard, in effect, combines the NBS standard of spectral radiance with a small aperture which approximates a point source of radiant energy of known spectral distribution. This combination, with one or more convex mirrors, will supply extremely low-spectral irradiances in the wavelength range 0.25 μ to 2.6 μ with an uncertainty of about 10%.
