摘要

摘要: 轴向梯度折射率(AGRIN)透镜是一种有望用来替代非球面，并在成像时优于非球面的一种方法。综述了AGRIN材料的发展历史，现状及其在镜头设计中的应用，简述AGRIN材料在光学设计中的应用和它与非球面相比的优点，探讨AGRIN材料的制造问题。发现使用AGRIN材料，不仅会使光学系统成像质量有所提高，而且在制造和测试上都有很大的优势。最后以设计一个焦距125mm、F/4、视场25，适用于DALSA全帧28M像素大幅面CCD的航测数字相机镜头为例，把原来的11片全球面镜头，利用2片AGRIN透镜，在保持像质不变的情况下减少到8片，而且像质均匀性和镜头结构更加合理。

Abstract: Axial gradient index (AGRIN) medium is hopeful to be substituted for the aspherical lens since the image quality of the former is better. The status and application of AGRIN lens are introduced. Its merits comparing with the aspherical lens are briefly presented. The manufacture technology of AGRIN medium is discussed. It is found that AGRIN material using in optical systems not only improves the image quality but also lowers the testing difficulties. A lens with 125mm focus, F/4, 25 FOV, which is suitable for full-frame 28 M pixel DALSA FTF6146M CCD, is designed for a digital aerial survey camera. Three spherical lenses were decreased from the original eleven ones because of the two AGRIN lenses on the premise of keeping the same image quality. The result indicates that the image uniformity and structure of the camera are much better than before.
