Problems solved by technology
[0003] The detection of the lens needs to take a test card in the test device to evaluate the image quality of the image captured by the lens. Currently, to test the quality of the image captured by the lens, different test devices need to be designed according to different specifications of the lens. For example, test The distance between the test card and the lens in the device needs to be adjusted according to the lens specification, which makes the lens detection efficiency low. In order to adapt to the detection of more lenses with different specifications, the size of the test device will also be large, and the cost of use is too high and inconvenient

The invention relates to the field of lens detection, and discloses a miniaturized lens testing device, which comprises a rack; the carrying table jig is used for installing the lens, and the carrying table jig is arranged on the rack; the test card mechanism is arranged opposite to the carrying table jig, and the test card mechanism is arranged on the rack, so that the lens is used for acquiring an image of the test card mechanism when being mounted on the carrying table jig; the relay lens mechanism is movably arranged on the rack, and when the relay lens mechanism moves to a test station, the relay lens mechanism is located between the test card mechanism and the carrying table jig; the optical axis of the relay lens mechanism coincides with the optical axis of the lens installed on the carrying table jig. The test device for detecting the lens is miniaturized, and the efficiency of detecting the imaging quality of the lens is improved.
Description
technical field [0001] The present invention relates to the technical field of lens detection, in particular to a miniaturized lens testing device. Background technique [0002] With the development of science and technology, more and more electronic products have increasing demands for lenses of different specifications and quality specifications, and various testing needs are also increasing due to lens products of different specifications. [0003] The test of the lens requires a test card to be shot in the test device to evaluate the image quality of the image captured by the lens. The existing test for the quality of the image captured by the lens requires different test devices to be designed according to different specifications of the lens. For example, testing The distance between the test card and the lens in the device needs to be adjusted according to the lens specifications, so that the lens detection efficiency is low. inconvenient.
