摘要

    摘要
  • 摘要: 随着手机市场对高像素手机镜头的需求增大，利用Zemax光学设计软件设计一款大相对孔径800万像素的广角镜头。该镜头由1片非球面玻璃镜片，3片非球面塑料镜片，1片滤光镜片和1片保护玻璃构成。镜头光圈值F为2.45，视场角2为68，焦距为4.25 mm，后工作距离为0.5 mm。采用APTINA公司的MT9E013型号800万像素传感器，最大分辨率为3 2642 448，最小像素为1.4 m。设计结果显示：各视场的均方根差（RMS）半径小于1.4 m，在奈奎斯特频率1/2处大多数视场的MTF值均大于0.5，畸变小于2 %,TV畸变小于0.3 %。
    Abstract: The high-pixel mobile phone camera is demanded with the development of mobile phone market. An 8 mega-pixel lens system with large relative aperture and large field of view (FOV) is designed with Zemax. The system includes one glass aspheric lens, three plastic aspheric lenses, an IR cut filter and a sensor cover glass. The F-number is 2.45 and FOV is 68,the effective focal length and back focal length are 4.25 mm and 0.5 mm respectively. The sensor MT9E013 have 8 mega pixels which is made by APTINA, the maximum resolution is 3264 x 2448 and the minimum pixel is 1.4 m.The design result shows that RMS spot radius at different fields are less than 1.4 m，the MTF value is more than 0.5 in most fields of view at 1/2 Nyquist sampling frequency. Distortion is less than 2%, and TV distortion is less than 0.3%.
