摘要
随着CMOS、CCD探测器的广泛应用及其分辨率的不断提高,人们对电视镜头的分辨率提出了更高的要求。将显微工业电视镜头成像原理与传统显微镜进行了比较,并利用光学设计软件ZEMAX进行光学效果的模拟,给出了数值孔径为0.08,光学放大倍数为1,焦距为38 mm,视场直径为8 mm,全视场角为10°,分辨率为200万像素的光学系统设计结果。所设计的显微工业电视镜头可用于工业生产检测。
With CMOS, CCD detector being widely used in optical instruments, and the improvement of the detector resolution, higher resolution of TV lens is demanded. The imaging theories of the industrial micro TV lens and the traditional microscope are compared. By using ZEMAX, the optical model results of industrial micro-lens are obtained. The designed results of 200 million pixels optical system are given when number aperture is 0. 08, optical magnification is 1, focal length is 38 mm, visual field diameter is 8 mm, full field is 10°. The design of micro TV lens can be used in the industrail field.
