| 摘 要： | 介绍了以摄远型为初始结构的宽光谱长焦距折射式物镜的设计方法。对玻璃材料的选择进行了分析,并建立了能够分配三分离透镜组光焦度的复消色差方程组。通过理论计算和ZEMAX光学设计软件的优化,给出工作波长范围在0.4~0.9μm、焦距为400 mm、视场角为6.2°、相对孔径为1∶4的设计实例。设计结果表明,二级光谱得到了很好的校正,像质优良。

| Abstract: | The design method of a refracting telephoto objective with wide spectral and long focal is introduced.Suitable glass materials for correction of secondary spectrum are analyzed,and the system of apochromatic equations for solving the range of each lens power in the triplet lens is established.A design example of a lens whose operating wavelength is 0.4～0.9μm,focal length is 400 mm,full field-of-view angle is 6.2° and relative aperture is 1:4 is given on the basis of the theoretical calculation and the optimization of optical design software ZEMAX.The result of design shows that aberration of secondary spectrum is well corrected and image quality is good. |
