Abstract

The application discloses a testing method and a testing system. The test method is used to test lenses, which include multiple lens groups under test. The test method includes: pairing a compensation lens group for at least one of the tested lens groups to form a composite lens, and the aberration of the compensation lens group is within a preset range; detecting the imaging definition of the composite lens; When the sharpness is greater than the preset imaging sharpness, it is determined that the quality of the tested lens group is up to the standard; when the imaging sharpness of the combined lens is lower than the preset imaging sharpness, it is determined that the quality of the tested lens group is not up to the standard. In this application, the compensating lens group and the tested lens group are paired into a combined lens, and the imaging definition of the combined lens is tested to determine whether the tested lens group meets the index requirements, which solves the problem of the quality of the individual lens group in the lens of multiple lens groups Test questions.

Description

technical field [0001] The present application relates to the technical field of optical imaging, in particular to a test method and a test system. Background technique [0002] For lenses with multiple lens groups, since each lens group has large aberrations and poor imaging quality when used alone, it is impossible to judge whether each lens group meets the requirements. Contents of the invention [0003] Embodiments of the present application provide a testing method and a testing system. [0004] An embodiment of the present application provides a testing method for testing a lens. The lens includes a plurality of tested lens groups. The test method includes: pairing a compensation lens group for at least one of the tested lens groups to form a composite lens, and the aberration of the compensation lens group is within a preset range; detecting the imaging clarity of the composite lens; When the imaging resolution of the combined lens is greater than the preset imag...
