大型综合巡天望远镜（LSST）是一种独特的三镜，改进的保罗-贝克设计，具有8.4米主镜，3.4米副镜和5.0米三镜，为相机系统提供包括校正光学系统在内的3.5度视场，具有出色的图像质量（<0.3弧秒80%的绕射能量），覆盖了从蓝色到近红外波长的整个视场。我们描述了LSST相机光学系统的设计，包括三个直径分别为1.6m、1.0m和0.7m的折射透镜，以及一组直径为0.75m的可互换宽带干涉滤光片。我们还描述了制造，涂层，安装和测试这些镜片和过滤器的当前计划。
The Large Synoptic Survey Telescope (LSST) is a unique, three-mirror, modified Paul-Baker design with an 8.4m primary, a 3.4m secondary, and a 5.0m tertiary feeding a camera system that includes corrector optics to produce a 3.5 degree field of view with excellent image quality (<0.3 arcsecond 80% encircled diffracted energy) over the entire field from blue to near infra-red wavelengths. We describe the design of the LSST camera optics, consisting of three refractive lenses with diameters of 1.6m, 1.0m and 0.7m, along with a set of interchangeable, broad-band, interference filters with diameters of 0.75m. We also describe current plans for fabricating, coating, mounting and testing these lenses and filters.
