一种紧凑型光学成像系统及镜头模组
By introducing an optical compensation layer and lens combination into the lens module, the light propagation path is optimized and chromatic aberration and spherical aberration are eliminated, solving the problems of simplifying and thinning the lens module and achieving high-quality miniaturized imaging effects.

Abstract
本申请公开了一种紧凑型光学成像系统及镜头模组，包括布置于物侧和像侧之间的透镜组，透镜组和像侧之间的光路上设置有一透光的光学补偿层，透镜组由从物侧至像侧依次布置的n个透镜构成，n为大于1的正整数，第n透镜与光学补偿层分别具有正屈光度和负屈光度，或分别具有负屈光度和正屈光度，光学补偿层适于对透镜组射向像侧的光线进行补偿调整，本申请通过添加额外的光学补偿层对像侧的感光芯片等元件进行密封和保护，同时将光学补偿层作为光学优化设计的一部分，利用光学补偿层本身的非球面特性来优化光线的传播路径，以保证光学成像质量的同时，降低光学成像系统的总高。
