A compact, efficient illumination system (9) has many advantages over conventional illuminators based upon integrating spheres. An elliptical light source/concentrator (13), preferably controlled by a light stabilization system (21) using optical feedback to control the light intensity, provides high spatial uniformity of high irradiance values can be produced over sizeable areas for testing large area detector arrays. The illuminator is simpler and more economical than traditional systems and provides extended wavelength coverage potential. The illumination system is easy to maintain.
