| 中文摘要: |
| 设计一种可用于监控系统的大孔径百万像素变焦距光学成像镜头,采用1/3英寸CCD接收,像元大小为3.75 μm。镜头在短焦、长焦位置时F数分别为1.6,2.1。利用Zemax工程光学设计软件,对镜头进行了设计与优化,并对优化后的结果进行了分析。设计的镜头在极限分辨率时,MTF较高,公差也相对较松,可以满足实际生产要求。 |
| 英文摘要: |
| A large diameter and megapixels zoom optical imaging lens with CCD image sensor for monitoring system was designed, and the size of CCD and the pixel was 1/3 inches and 3.75 μm respectively. F numbers of lens in the position of short-focus and long-focus were 1.6 and 2.1 respectively. The lens was designed and optimized by using Zemax optical design software, and the optimized results were analyzed.The design of lens MTF is higher, tolerance is rather loose which meets the requirements in practical manufacture. |
