摘　　要：校正镜组是大口径大视场望远镜的核心组件。为了满足透镜面形和成像质量等光学设计要求,透镜支撑结构的设计与安装对准方式的选择尤为重要。本文详细介绍三种透镜支撑结构,压圈隔圈支撑、RTV弹性体支撑和柔性结构支撑,并对三种支撑方式优缺点进行比较。结合实例总结了校正镜组的安装对准方式,对大口径大视场望远镜校正镜组的支撑结构设计及安装方式确定具有非常好的借鉴意义。Wide Field Corrector is the prime component of large aperture wide field telescope.In order to meet the requirements of optical design,such as lens shape error and image quality,the choice of lens support assembly and alignment is particularly important.In this paper,three kinds of lens support structures,pressure ring spacer support,RTV elastomer support and flexible support are introduced in detail,and the advantages and disadvantages of the three support methods are compared.The installation and alignment mode of the calibration lens set with an example are summarized,which has a very good reference significance for the design of the support structure of the calibration lens set of the large-diameter large-field telescope and the determination of the installation mode.
