下一代CMB天文台CMB-S4将部署数十万个探测器，以前所未有的速度绘制毫米波长的天空。CMB-S4的大口径望远镜由6米直径的交叉Dragone设计和5米直径的三镜反射镜组成。双镜交叉Dragone设计需要在折射光学器件中进行像散校正以实现衍射限制性能。我们提出了双锥透镜校正的CMB-S4交叉Dragone相机的光学和比较这些设计的相机光学的三反射镜反射镜，因为这些望远镜的相机的光学设计正在原型。
CMB-S4, the next-generation CMB observatory, will deploy hundreds of thousands of detectors to enable mapping the millimeter-wavelength sky with unprecedented speed. The large aperture telescopes for CMB-S4 consist of six-meter diameter crossed Dragone designs and a five-meter diameter three-mirror anastigmat. The two-mirror crossed Dragone design requires astigmatism corrections in the refractive optics to achieve diffraction-limited performance. We present biconic lens corrections for the CMB-S4 crossed Dragone camera optics and compare these designs to the camera optics for the three mirror anastigmat, as the optical designs of the cameras for these telescopes are being prototyped.
