Abstract

The application discloses a testing method and a testing system. The test method is used to test the lens. The test method includes: sending test light toward the reflector along a predetermined direction through a light source; driving the reflector to move along the optical axis direction of the lens through a driving member; receiving the test light reflected back by the reflector through a light receiving screen to obtain a return light point; The positional relationship between the light spot and the reference light spot determines whether the lens is qualified. The test method and test system of the embodiment of the present application emit test light toward the reflector driven by the driver, determine whether the lens is qualified by the positional relationship between the return light point of the test light and the reference light point, and complete the test with a simple mechanical structure. Whether the lens is qualified can be accurately judged, which is beneficial to improving the testing efficiency and improving the quality assurance of the tested lens.

Description

technical field [0001] The present application relates to the technical field of lens inspection, in particular to a testing method and testing system. Background technique [0002] In the optical lens, the forward and backward movement of the lens group is driven by a voice coil motor. During the process of moving the lens group along the optical axis driven by the motor, since the entire moving stroke is relatively long, the lens group is often accompanied by inclination in addition to the positional movement along the optical axis. This inclination will bring about a decline in the imaging quality of the lens, resulting in serious effects such as unclear imaging. Therefore, there is an urgent need for a detection method to judge whether the imaging quality of the lens is qualified. Contents of the invention [0003] Embodiments of the present application provide a testing method and a testing system. [0004] The test method in the embodiment of the present applicati...
