Abstract

The invention discloses a test method and a test system. The test method is used for testing a camera lens; and the camera lens comprises a plurality of tested lens groups. The test method comprises the following steps that: at least one tested lens group is paired with a compensation lens group, so that a combined lens can be formed, the aberration of the compensation lens group is within a preset range; the imaging definition of the combined lens is detected; when the imaging definition of the combined lens is greater than preset imaging definition, it is determined that the quality of the measured lens group reaches a standard; and when the imaging definition of the combined lens is smaller than the preset imaging definition, it is determined that the quality of the measured lens groupdoes not reach the standard. According to the test method of the invention, the compensation lens group and the tested lens group are paired to form the combined lens; the imaging definition of the combined lens is tested, so that whether the tested lens group meets index requirements can be determined, and the problem of the quality testing of a single lens group of a camera lens comprising a plurality of lens groups can be solved.

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...
