DECam仪器，用于CTIO的4米布兰科望远镜，是一个5透镜元件宽视场相机，提供2.2度直径的视场。镜头很大，最大的直径为980毫米，这对安装和对准提出了挑战。本文报告了DECam宽视场成像仪光学元件的生产状况。还介绍了成像仪5个透镜单元设计的设计和有限元建模沿着拟议的对准过程。
The DECam instrument, for the 4m Blanco telescope at CTIO, is a 5 lens element wide field camera giving a 2.2 degree diameter field of view. The lenses are large, with the biggest being 980mm in diameter, and this poses challenges in mounting and alignment. This paper reports the status of the production of the optics for the DECam wide field imager Also presented are the design and finite element modelling of the cell design for the 5 lenses of the imager along with the proposed alignment process.
