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.   All reflective zoom systems for infrared optics (EI CONFERENCE) 会议论文  OAI收割 International Optical Design Conference 2006, June 4, 2006 - June 8, 2006, Vancouver, BC, Canada 作者:  Wang Y.;  Yang H.;  Zhang T.;  Wang Y.;  Wang Y. 收藏  |  浏览/下载：30/0  |  提交时间：2013/03/25 The results of design effort for infrared zoom systems using all reflective aspheric surfaces are described. Issues such as the paraxial design theory and aberration balancing are discussed in detail. Two all reflective zoom optical systems are disclosed clearly. Both of them are to be used with uncooled infrared detectors. The first design is an unobscured three mirror zoom system without any intermediate image  and the second is a three mirror system with central obscuration which forms an intermediate image. With the design theory further developed  this kind of systems can be designed for cooled infrared detectors  for which cold stop matching is an important issue. 2006 SPIE-OSA.
