Description

摄像光学镜头 技术领域
本发明涉及光学镜头领域，特别涉及一种适用于智能手机、数码相机等手提终端设备，以及监视器、PC镜头等摄像装置的摄像光学镜头。
背景技术
近年来，随着智能手机的兴起，小型化摄影镜头的需求日渐提高，而一般摄影镜头的感光器件不外乎是感光耦合器件(Charge Coupled Device，CCD)或互补性氧化金属半导体器件(Complementary Metal-Oxide Semiconductor Sensor，CMOS Sensor)两种，且由于半导体制造工艺技术的精进，使得感光器件的像素尺寸缩小，再加上现今电子产品以功能佳且轻薄短小的外型为发展趋势，因此，具备良好成像品质的小型化摄像镜头俨然成为目前市场上的主流。
为获得较佳的成像品质，传统搭载于手机相机的镜头多采用三片式、四片式甚至是五片式、六片式透镜结构。然而，随着技术的发展以及用户多样化需求的增多，在感光器件的像素面积不断缩小，且系统对成像品质的要求不断提高的情况下，七片式透镜结构逐渐出现在镜头设计当中，常见的七片式透镜虽然已经具有较好的光学性能，但是其光焦度、透镜间距和透镜形状设置仍然具有一定的不合理性，导致透镜结构在具有良好光学性能的同时，无法满足大光圈、超薄化、广角化的设计要求。
