| 摘 要： | 利用CODE V光学软件设计了一种用于内调焦对心器的电视测微镜头。该镜头由四片透镜组成,采用正负正焦距对称结构。其焦距为17.20 mm,数值孔径为0.063,视场为16.82°。该镜头工作在486～656 nm波段,总长为68 mm。系统的全视场畸变为-1.13%,调制传递函数MTF值在空间频率为60 lp/mm时大于0.64。设计结果表明,该系统的成像质量良好,结构紧凑,满足使用要求。

| Abstract: | The CODE V optical design software is used to design a TV micrometric lens for a centering item with an inner adjusting focus. The lens is composed of four lenses. It has a symmetric structure with positive and negative focal lengths. Its focal length, numerical aperture and field of view are 17.20 mm, 0.063 and 16.82° respectively. The lens operates in the waveband from 486 nm to 656 nm. Its total optical length is 68 mm. It has the maximum distortion of 1.13% in the full field of view and the modulation transfer function greater than 0.64 at a space frequency of 60 lp/mm. The design result shows that the system has good imaging quality and a compact structure which meet the practical requirements. |
