Cassegrain reflector - Wikipedia
The Cassegrain reflector is a combination of a primary concave mirror and a secondary convex mirror, often used in optical telescopes and radio antennas, the main characteristic being that the optical path folds back onto itself, relative to the optical system's primary mirror entrance aperture.

Schmidt-meniscus Cassegrain 施密特弯月形卡塞格林 这种类型的望远镜可谓是集合了施密特和马克苏托夫的优点，相当于是叫了两种校正器，施密特用于校正 球差 ，弯月用于校正慧差，不过这种类型的卡塞格林长度显得有些过长，不适合大口径的使用。

1609年伽利略通过延续荷兰商人的发现，发明了第一台折射式望远镜，极大推进了人类观察太空的进程。随后， 开普勒 又在其基础上发明了另外一种望远镜— 开普勒式望远镜 。 受限于当时的加工水平，大口径的折射式望远镜很难实现，并且折射式望远镜非常的笨重，在观察时有色差影响，并 …
Cassegrain reflector | Optical Telescope, Reflective Optics, …
Cassegrain reflector, in astronomical telescopy, an arrangement of mirrors to focus incoming light at a point close to the main light-gathering mirror. The design was proposed in 1672 by French priest Laurent Cassegrain.
Two-mirror telescopes: Cassegrain, Gregorian and variants
Classical two-mirror arrangements are Gregorian - the very first reflective telescope design, conceived by James Gregory in 1663 - and Cassegrain (FIG. 121), probably introduced in 1672 by Laurent Cassegrain. In the former, concave secondary mirror is placed outside the focal point of the primary mirror, and in the latter the secondary is ...

2020年5月5日 · 今天，我们介绍PSM如何用来装调Cassegrain type telescope(卡塞格林望远镜)系统。 一、PSM结构原理图图一、PSM原理图PSM的原理如图一所示，如果物镜的焦点精确定位在球面镜的曲率中心，则 反射 光会在探测器的中心位置聚焦成一个缩小的点。
A Classic Cassegrain Telescope For The Modern World
2024年6月4日 · The Cassegrain, or Classical Cassegrain as it has become known, is a well-corrected, two mirror telescope that was developed by Laurent Cassegrain and is the foundational design of many of the most popular telescopes today.
Cassegrain Telescope: Classical Design, Advantages, Comparison
2023年10月21日 · Cassegrain telescope equations allow telescope users to calculate and understand the behavior of light as it reflects off the mirrors. By knowing the relationship between the focal lengths and the radii of curvature, observers optimize the telescope’s design for specific tasks or observational priorities.
Cassegrain - an overview | ScienceDirect Topics
A cassegrain design employs a parabolic primary mirror and a parabolic or a hyperbolic secondary mirror. There are several designs of cassegrain based on the position and surface of mirrors.
