The invention discloses a low-cost unmanned aerial vehicle airborne infrared temperature measurement lens which comprises a front fixing group and a focusing group which are sequentially arranged from the object side to the eye side. The focal power of the front fixing group is positive; the focal power of the focusing group is negative; a first lens L1 is accommodated in the front fixed group; a second lens L2 is accommodated in the focusing group; the first lens L1 is a positive meniscus lens; the second lens L2 is a biconvex lens; the first lens rear surface S2, the second lens front surface S3 and the second lens rear surface S4 are all aspheric surfaces. The lens is stable in transmission, compact in mechanism and convenient to assemble, and has high imaging quality and high spatial resolution of MTF (on-axis (at) 40lp/mm) greater than or equal to 0.5.
本申请公开了一种低成本无人机机载红外测温镜头,包括从物侧向目侧依次设置的前固定组、调焦组;前固定组的光焦度为正;调焦组的光焦度为负;前固定组内容纳设置第一透镜L1;调焦组内容纳设置第二透镜L2;第一透镜L1为正弯月透镜;第二透镜L2为双凸透镜;第一透镜后表面S2、第二透镜前表面S3、第二透镜后表面S4均为非球面。该镜头传动平稳、机构紧凑、便于装配,具有MTF(轴上@40lp/mm):≥0.5的高成像质量、高空间分辨率。
