一、反射式光学定中心装置的运动原理随着电子计算机在光学设计中的广泛应用,光学设计进入了一个新的阶段。目前设计一个高质量的镜头或光学系统已不是十分困难的问题了,但是制造误差却直接影响光学系统的成象质量,其中最重要制造误差之一就是中心偏。在设计上目前已有各种方法来计算光学系统中各零件允许的中心偏。尽管为了保证这些零件在光学系统中的正确位置所采取的一系列措施是多种多样的,但是它们都必须首先把光学表面的球心校正到基准轴上,或者说使光学表面的球心以给定的精度与基准轴重合,这就是所谓的定中心。在此基础上才能进行加工或
First, the reflective optical centering device movement principle With the widespread use of electronic computers in optical design, optical design has entered a new phase. At present, designing a high-quality lens or optical system is not a very difficult issue. However, the manufacturing error directly affects the imaging quality of the optical system. One of the most important manufacturing errors is center deviation. In the design, there are various methods for calculating the allowable center deviation of each part in the optical system. Although a number of measures are taken to ensure the correct placement of these components in the optical system, they must first correct the sphere center of the optical surface to the reference axis or the sphere center of the optical surface The given accuracy coincides with the reference axis, which is called centering. On this basis can be processed or
