前言单色仪是一种用途非常广泛的分光仪器。人们对单色仪感兴趣的主要特性是分辨率、色散率和集光本领。使用者希望单色仪能够出射单色性好而强度又高的单色光。目前国内有许多类型的棱镜或光栅单色仪,它们大多数是把色散元件放在平行光束中,这样产生的像差小。利用准直物镜和成像物镜对消像差,可以获得较高的分辨率。为了得到高分辨率,一般光学系统的相对口径都不大,常在1∶6～1∶10之间。如果再增大相对口径,要给设计和制造
Introduction Monochromator is a very versatile spectrometer. The main features people are interested in monochromator are the resolution, dispersion rate, and the ability to collect light. The user wants the monochromator to emit monochromatic light of good monochromaticity and high intensity. At present, there are many types of prism or grating monochromator in China, most of them put the dispersive element in a parallel beam, thus producing small aberrations. The use of collimating objectives and imaging lens on the elimination of aberrations, you can get a higher resolution. In order to obtain high resolution, the relative optical system generally are not large, often between 1: 6 ~ 1:10. If you increase the relative size, to give the design and manufacture
