我们描述了智利塞罗·托洛洛美洲天文台（CTIO） 4米布兰科望远镜主焦的五元校正器，它将与一个新的马赛克CCD相机一起使用，作为拟议的暗能量调查（DES）的一部分。该校正器设计用于在SDSS g、r、i和z滤光片中提供平坦的焦平面和良好的图像。我们结合DES的科学要求描述了性能，特别是关于重影和弱透镜点扩展函数（PSF）校准。
We describe a five element corrector for the prime focus of the 4 meter Blanco telescope at the Cerro Tololo Inter-American Observatory (CTIO) in Chile that will be used in conjunction with a new mosaic CCD camera as part of the proposed Dark Energy Survey (DES). The corrector is designed to provide a flat focal plane and good images in the SDSS g, r, i, and z filters. We describe the performance in conjunction with the scientific requirements of the DES, particularly with regard to ghosting and weak-lensing point spread function (PSF) calibration.
