Lens projection system for a solar simulator providing irradiance of 100 solar constants

Algebraic design equations were derived for an optical projection system that included lenticular plates and a collimating lens. The system was applied to a solar simulator using a 20-kW xenon lamp. It produced an irradiance of 100 solar constants that was uniform to 1% within the volume of space occupied by a test model whose dimensions were of the order of 10 cm.
