一、问题的提出设计长焦距光学系统的一个突出问题是校正二级光谱。为此,我们在设计一个长焦距照相镜头中,曾采用下面办法。由初级象差理论,各组透镜都有: 解出
First, the issue put forward Design Long focal length optical system is a prominent problem is to correct the secondary spectrum. For this reason, we have used the following method in designing a telephoto lens. From the primary aberration theory, each lens has: solved
