The unmanned aerial vehicle imaging lens comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens, a ninth lens, a tenth lens, an eleventh lens, a twelfth lens, a thirteenth lens and a fourteenth lens which are sequentially arranged from the object side to the image side. The first lens is a meniscus lens with positive diopter, and the convex surface of the first lens faces the object surface; the second lens is a meniscus negative diopter lens, and the convex surface faces the object surface; the third lens is a meniscus lens with negative diopter, and the convex surface faces the object surface; according to the technical scheme, fourteen lenses are combined, and the diopters, shapes and materials of the optical lenses are reasonably matched and combined, so that the unmanned aerial vehicle imaging lens with the focal length of 6.6 mm, the unmanned aerial vehicle imaging lens with the wavelength of visible light, the field angle of 104 degrees and the aperture F of 2.8 and the target surface of 1 inch can be ensured, and infinite-distance imaging can be realized; and the requirements of low distortion and achromatism are met.

    本发明公开了一种无人机成像镜头,包括自物侧到像侧依次设置的:第一透镜、第二透镜、第三透镜、第四透镜、第五透镜、第六透镜、第七透镜、第八透镜、第九透镜、第十透镜、第十一透镜、第十二透镜、第十三透镜、第十四透镜;所述第一透镜为弯月型正屈光度透镜,凸面朝向物面;所述第二透镜为弯月型负屈光度透镜,凸面朝向物面;所述第三透镜为弯月型负屈光度透镜,凸面朝向物面;本技术方案采用十四片透镜组合,通过对各光学镜片的屈光度、形状、材料进行合理的搭配和组合,满足上述配置有利于保证焦距为6.6mm的无人机成像镜头,波长为可见光,视场角为104°,光圈F为2.8的1英寸靶面无人机成像镜头,能够无穷远成像,满足低畸变、消色差的要求。
