Many optical systems are designed to operate with radiation that is received from distant point sources such as stars or target hot-spots. In order to test such systems, one must build a star simula-tor that spatially filters the radiation from a laboratory source. In this paper, we will discuss the design principles for such a simulator. The design becomes complicated in that the spatial filter assembly also provides spectral filtering on the laboratory source. This effect is calculated and various compensation methods are discussed.
