| description | The utility model discloses a relay lens and a lens module detection device. The relay lens at least comprises a first lens and a second lens which are arranged in sequence, and the first lens and the second lens are combined into a convex lens group which is provided with a positive focal distance. The lens module detection device includes the relay lens and a virtual resolution plate which is used for projection imaging, wherein the second lens of the relay lens faces the virtual resolution plate, and the virtual resolution plate is oppositely arranged out of a distance twice the focal distance of the relay lens. During the detection, the lens module to be detected is placed on the side close to the first lens of the relay lens and is placed within the distance twice the focal distance of the relay lens, and the lens module generates an image on the virtual resolution plate via the relay lens. Therefore, the quality of the lens module can be judged through the imaging quality of the virtual resolution plate |
