球棱镜及其应用

现代科技的迅速发展促进了非共轴光学系统的发展和日益广泛的应用。球棱镜是非共轴光学系统常采用的光学元件之一。合理采用球棱镜元件可以设计出一系列具有不同用途的光学系统。它们具有尺寸小、重量轻、结构紧凑等特点，并且具有共轴光学系统难以达到的一些光学性能，因而也拓宽了光学系统的应用范围。本文从非共轴光学系统出发，对球棱镜的种类和性能特点进行了阐述，并介绍了其在非共轴光学系统中的几种应用。

Sphere-prism and Its Application

: The repid development of modern science and technology accelerates the development of uncoaxial optical system and its extensive application. Sphere prism is one of the elements often used in an uncoaxial optical system. Reasonably using a sphere prism, a series of optical systems with different applications can be designed. These systems have the advantages of small small size, less meight and compact structure, and have some optical features which is hardly achieved by a coaxial optical system,expanding the applications of optical system. The types and characteristics of sphere prism are discussed, and some applications of it in the uncoaxial optical system are presented.
