Small TOF lens

The invention relates to a small TOF lens. The small TOF lens comprises a first lens body, a second lens body, a third lens body, a diaphragm, a fourth lens body, a fifth lens body and a sixth lens body which are sequentially arranged from front to back in the light incident direction. The small TOF lens overcomes the defects that an existing TOF lens is large in total optical length, not high inimaging quality and the like, the two plastic aspheric lenses are applied to be matched with other specially-designed lenses in a lens system, TV distortion can be well corrected in the design of a large aperture, the total optical length is reduced, the structure is small, and the imaging quality is high. 本发明涉及一种小型TOF镜头，包括沿光线入射方向从前至后依次设置的第一透镜、第二透镜、第三透镜、光阑、第四透镜、第五透镜与第六透镜。该发明克服了现有TOF镜头存在的光学总长大、成像质量不高等缺点，本发明提供一种小型TOF镜头，运用了两片塑料非球镜片，其与镜片系统中的其他经过特别设计的镜片的配合，可以很好地在大光圈的设计中矫正TV畸变并减小光学总长，以实现结构小巧且成像质量高。
