Paper Abstract

Application-specific integrating sphere-based, integral veiling glare measurement systems are described. The sources use the integral method for measuring the veiling glare (VG) index of various lens-based imaging systems. The calibration source has provisions in the form of a collimating lens holder to simulate a situation where the black target and bright surround are at a sufficiently great distance to give measurements of VG index which are the same as that which would result if the distance where infinite. The design criteria for the integral VG test source are presented. Included is a summary of the end-user specifications in regards to spectral radiance, levels of attenuation, irradiance stability, and aperture uniformity and contrast. Spectral radiometric predictions and actual output levels are compared.
