256兆像素成像器OmegaCAM将成为欧洲南方天文台帕拉纳尔天文台VLT测量望远镜的广域相机。该相机将在2.6米长的VST望远镜上覆盖1平方度的视野，分辨率为16k×16k。光学和机电设计是由荷兰-德国-意大利财团负责的，而低温探测器系统是由欧洲南方天文台建造的。设计阶段已在2001年秋季成功地进行了最后设计审查。采购和制造一直持续到2002年底，随后是在欧洲初步验收之前的一段广泛的测试期。本文将介绍相机的设计，包括设计分析和性能评估的结果，其中重点是光学和有限元分析。此外，还将讨论大尺寸滤光片的实际设计。他们的采购被证明是一个具有挑战性的问题。
The 256-Mega-Pixel imager OmegaCAM will become the wide-field camera at the VLT-Survey-Telescope of the ESO Paranal Observatory. The camera will cover 1 square-degree field of view at the 2.6-metre VST telescope with 16k×16k pixel resolution. The opto- and electro-mechanical design is the responsibility of a Dutch-German-Italian consortium whereas the cryogenic detector system is built by ESO. The design phase had been finalized with a successful Final-Design-Review in autumn 2001. Procurement and manufacturing is ongoing till the end of the year 2002 followed by an extensive testing period before Preliminary-Acceptance-in-Europe. The paper will present the camera design including the results of design analyses and performance assessments of which optical and finite-element-analyses will be emphasized. The actual design of large-format optical filters will be addressed as well. Their procurement turned out as a challenging issue.
