这里提出了计算机辅助设计等转角可变光栏的一种方法,并利用ALGOL—60语言编制了计算程序。一等转角条件孔径可变的光栏是镜头设计中经常遇到的一个元件,它主要由三部分组成:(图1)光栏座,光栏片和光栏转环。由六至十几片光栏片构成的多边形光孔,决定通光口径的大小。光栏片的工作边通常为直线或圆弧。在光栏片的两面铆或焊接两个销钉,其中一个插入光栏座
Here we present a method of computer-aided design such as corner variable light bar, and use ALGOL-60 language to compile the calculation program. First-class corner conditions Variable aperture diaphragm is often encountered in the lens design of a component, which is mainly composed of three parts: (Figure 1) light bar seat, diaphragm and light bar swivel. By the six to a dozen pieces of light film composed of polygonal aperture, determine the size of the aperture. The working edge of the diaphragm is usually a straight line or arc. Two pieces of rivets are welded or riveted on both sides of the diaphragm, one of which is inserted into the bezel
