charge coupled device（CCD） optical imaging lens optimization

摘要

Abstract

The design of a large-aperture and wide-band optical lens for camera is presented. By utilizing the atmospheric window of infrared light, clear images can be achieved in the dark or poor visibility conditions. To use near-infrared and visible light to obtain images, the charge coupled device(CCD) is adopted as the image sensor of the lens with the center wavelength of 880 nm, which operates at the wavelength range from 400 nm to 1 000 nm. After calculating the parameters of optical lens, Sunnah type is seleselected as the initial structure. Through the optimization of optical design software ZEMAX, the lens obtains an excellent imaging performance. The modulation transfer function( MTF) can be more than O. 3 at the spatial frequency of 110 lp/mm, and the maximum distortion can be less than 0.1%.
