Abstract
The application discloses an imaging lens, which comprises a focusing group, a prism and a fixed group; wherein the focusing group has positive refractive power and comprises four lenses with refractive power; the fixed group has positive refractive power and comprises seven lenses with refractive power; the prism is arranged between the focusing group and the fixed group; when the object distance changes, the imaging lens is focused by adjusting the position of the focusing group relative to the prism.
