To obtain a number of advantages in fabrication  testing and alignment  many designs in which spherical mirrors replace classical Cassegrain-form aspheric mirrors are present in the literature. However  spherical mirrors suffer from substantial spherical aberration and thereby require some form of corrector group. But in this case  the question encountered is that of making the basic optical configuration more complex. In this paper  a new design based on Cooke corrector group is presented for eliminating spherical aberration  which is believed to provide higher performance with less complexity than previous approaches. Besides  the cost and fabrication period will be extremely decreased. The telescope system using corrector group here can achieve good optical performance with f# of 10  full field of 0.5  obscuration of 1/3 and MTF (Modulation Transfer Function) of 0.48 corresponding to 50@lp/mm. 2009 Copyright SPIE - The International Society for Optical Engineering.
