摘要
在大截面传像束前置光学物镜设计中，采用“负-正”型式的像方远心光路结构，很好地解决了镜头轴外像差校正和像面照度均匀性问题，同时使镜头结构紧凑、小型化。给出了前置物镜设计实例：工作波长0．8～1．1μm，焦距5mm，相对孔径为1：3．84，光学长度为47mm，视场角为60°。在光学耦接镜设计中采用物方远心光路结构，引入二元光学透镜，通过理论计算和ZEMAX光学软件优化，给出工作波长0．8～1．1μm，焦距33．6mm，光学长度为63．5mm，采用一个衍射面的耦接镜设计实例。该设计结果适用于单丝直径16μm，截面直径6mm的光纤传像束。
To improve the imaging quality of the objective, and make the lens small in size, compact in structure, and uniformity at its image plane illumination, an objective is designed with ＂negative-positive＂ telecentric structure in the image space. The result of design shows that operating wavelength, angle of view, focal length, relative aperture, optical length respectively is 0.8-1.1μm, 60°,5mm,1：3.84, and 47mm. The coupling lens with one diffractive surface, telecentric structure in the object space is performed with calculation and optimization of optical design software ZEMAX, whose operating wavelength, focal length, field of view, optical length respectively is 0.8-1.1μm, 33.6mm, 6mm, and 63.5mm. The result is available for the imaging fiber bundle, whose single core diameter is 16μm, and section diameter is 6mm.
