任何一种镜头的光学系统设计对各种象差的校正都是在理想情况下进行计算的。但是实际生产中由于受光学零件本身的制造误差,(如曲率半径、厚度的误差)玻璃材料和镀膜质量等因素影响外,在很大程度上影响物镜质量的是,由于联接各光组透镜的机械结构不良(包括结构设计、零件加工以及装调等),而不能保证各光组透镜相互位置的准确性。其中以各组透镜光轴与镜简内园机械轴的不同心误差影响最大。所以镜头设计应根据不同的使用要求,首先选择合适的光学结构形式进行光学设计,确定光学参数;并根据象差的校正情况
The optical system design of any kind of lens corrects for various aberrations under ideal conditions. However, the actual production due to the manufacture of optical parts of the error, (such as the curvature radius, the thickness of the error), glass material and coating quality and other factors, to a large extent affect the objective lens quality is due to the connection of the light lens Poor mechanical structure (including structural design, parts processing and installation, etc.), but can not guarantee the accuracy of the mutual position of each light lens. Among them, each group of lens axis and mirror Jianzhong Park mechanical axis of the greatest impact of different heart error. Therefore, the lens design should be based on different requirements, first select the appropriate optical structure for optical design, determine the optical parameters; and according to the correction of aberrations
