马克苏托夫望远镜



马克苏托夫望远镜(Maksutov telescope)是折反射望远镜(面镜-透镜),设计目的为减少离轴的像差,例如彗形像差。
在1944年,苏联光学家德密特利·马克苏托夫(俄文:Дмитрий Дмитриевич Максутов)发明此型望远镜,在设计上以球面镜作主镜并结合在入射光孔的弯月形的修正壳以改正球面像差,这是在反射望远镜和其他类型上的重大问题。马克苏托夫式的最大缺点是不能制作大口径的(>250毫米/10英吋),因为受到修正板的抑制,重量和制作成本都会上扬。

Maksutov telescope 马克苏托夫望远镜![]() ![]() ![]() ![]() The Maksutov is a catadioptric telescope design that combines a spherical mirror with a weakly negative meniscus lens in a design that takes advantage of all the surfaces being nearly "spherically symmetrical". The negative lens is usually full diameter and placed at the entrance pupil of the telescope (commonly called a "corrector plate" or "meniscus corrector shell"). The design corrects the problems of off-axis aberrations such as coma found in reflecting telescopes while also correcting chromatic aberration. It was patented in 1941 by Russian optician Dmitri Dmitrievich Maksutov. Maksutov based his design on the idea behind the Schmidt camera of using the spherical errors of a negative lens to correct the opposite errors in a spherical primary mirror. The design is most commonly seen in a Cassegrain variation, with an integrated secondary, that can use all-spherical elements, thereby simplifying fabrication. Maksutov telescopes have been sold on the amateur market since the 1950s. |
