| 摘 要： | 利用ZEMAX光学软件设计出了一款适用于0.55″单片DLP微型投影机的广角数字微型投影镜头。镜头结构由6组8片镜片组成，具有结构简单、体形小、易加工、成本低等特点。镜头的有效焦距为8.25 mm，相对孔径为1/2.2，全视场角为80.5°，最大口径小于24 mm，光学总长控制在40 mm，后工作距离为24 mm。镜头有较好的成像质量，在镜头的分辨率66 lp/mm处，所有视场的MTF值均大于0.45，全视场畸变量的绝对值小于0.7%，垂轴色差小于0.5个像元大小。

| Abstract: | A wide-angle digital mini-projection lens applied to 0.5″digital light processing(DLP) projectors was designed with ZEMAX. The structure is composed of 8 lenses. It is characterized by simlicity,compactness,low cost and easy processing.The effective focal lenth of the lens is 8.25 mm, F number is 2.2, field of view (FOV) is 80.5°, the maximum diameter is less than 24 mm,the optical total track is 40mm and the back working distance is 24mm. Its modulated transfer function (MTF) in all fields is higher than 0.45 at 66 lp/mm. The absolute value of the full FOV distortion is less than 0.7%. The lateral chromatic aberration is less than 0.5 pixel .The image quality of the lens is very good. |
