	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：33/0 \| 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.
