Abstract

The invention relates to a relay mirror apparatus used for lens detection, and more particularly to a relay mirror lens available for dual camera shooting module detection. The relay mirror lens comprises a lens barrel, wherein a mounting cavity passing through both sides of the lens barrel is formed in the lens barrel, the left side of the lens barrel is a test end opposite to a lens to be tested, the right side of the lens barrel is an imaging end opposite to a test graphic card, a first lens and a second lens are in contact with each other, a third lens and the second lens are disposed at an interval, a fourth lens and the third lens are disposed at an interval, the fourth lens and a fifth lens are in contact with each other, and an optical system composed of the first lens, the secondlens, the third lens, the fourth lens and the fifth lens enables the test graphic card at the imaging end to be shot by means of the optical system when the center of the lens to be tested at the testend deviates from an optical axis of the optical system by a certain range.

Description

【Technical field】 [0001] The application relates to a relay mirror instrument for lens inspection, in particular to a relay mirror lens that can be used for dual camera module inspection. 【Background technique】 [0002] The relay mirror is a relatively short simulation distance that can be used to capture pictures at different test distances required to evaluate the imaging quality of high-pixel cameras, which effectively reduces the scope of the test space, but the existing medium Most of the secondary mirror lens is to align the center of the test lens with the center of the secondary mirror for shooting and imaging detection, so that only one camera module can be detected at a time, and it requires high position accuracy. It needs to be adjusted, resulting in low efficiency, and the simulation range of the existing relay lens is at least greater than 200mm, which is not convenient for testing the close focus of the lens. 【Content of invention】 [0003] In order to solv...
