在我们观看宽银幕电影的时候,自然就会想到,宽银幕电影放映机与普通银幕电影放映机有什么区别,其实区别就在放映镜头上。例如,在普通的35毫米放映机上加一个A100-35宽银幕镜头就可以将画面在水平方向扩大一倍,放映宽银幕电影。A100-35宽银幕镜头由六片柱面透镜组成,柱面透镜的形状有双凹、平凹、双凸和平凸四种。柱面透镜的研磨与抛光有什么特点,如何才能高效率地加工柱面透镜,这些就是本文要讨论的内容。
When we watch widescreen movies, it is natural to think of the difference between a widescreen movie projector and a normal movie projector. In fact, the difference lies in the projection lens. For example, adding an A100-35 wide-screen lens to a regular 35mm projector can double the screen horizontally to show widescreen movies. A100-35 wide-screen lens consists of six cylindrical lenses, cylindrical lens shape double biconvex, flat concave, biconvex and flat convex four. Cylindrical lens grinding and polishing what are the characteristics, how to efficiently process cylindrical lens, these are the topics to be discussed in this article.
