Abstract

This paper describes the properties of two transfer standard sources developed to improve the accuracy of dissemination of spectral irradiance and radiance. The sources both make use of a novel concept, detector stabilization and monitoring, which allow the sources to provide high accuracy calibrations over a period of time more than four times that of conventional sources. Such sources have applications in many technology sectors but they are of particular relevance to the Earth Observation community as they offer high reliability in different environmental conditions and are less susceptible to change on transportation. The radiance source has the additional property of providing an extremely spatially uniform output, <+/- .02% at 380 nm over 80 mm diameter.
