摘要
介绍了一种含三个非球面的卡塞格林系统的设计思想,给出了一个设计结果。焦距2.8m,F/5.6,视场3.2°,主镜、次镜均为6次方非球面,场镜含一4次方非球面,成像质量接近衍射极限,畸变也得到了校正。
The design idea for Cassagrain system with three aspherical surfaces is presented. A design result for focal lenth of 2.8 m, F/5.6, field of view 3.2°, is obtained. The primary and secondary mirror have six order terms aspherical surfaces and the field lens has four oder terms aspherical surface. The image quality is close to the diffraction limit and the distortion is also corrected.
