Abstract

Abstract : Many small uniform sources are integrating spheres often with a 1 % nonuniformity. By placing a cylindrical element between the two hemispheres we were able to reduce the nonuniformity to approximately 0.1 %. This makes such a calibration source much less sensitive to detector measurement‐field size at the exit port.
