In the process of lens with aspherical surfaces，the aspherical surfaces and spherical surfaces are usually optically processed based on the structure of the lens.There is a machining eccentricity error between the symmetry axis of the aspheric surface and the opcical axis of the lens.The inconsistency between the asymmetrical axis and the optical axis of the optical system which contains multiple aspherical lenses and has strict eccentricity requirements ,such as the adjustment tolerance is 5″, leeds to a large wave aberration,if the adjustment of optical system is relied on the traditional decentering technology. The result reduces the final imaging quality of the lens.For the high-precision installation of aspherical refraction lens which contains strict installation tolerance,based on the traditional technology that adjusts the optical axis of the lens by devices such as center deviation measuring instruments,computer simulation calculation、 optimization of structural form and reasonable setting of compensator are applied in the actual engineering.According to the system aberration and compensator sensitivity, adjust the centered lens to reduce or eliminate the system aberration.The result shows that this method can effectively correct the misalignment of the system and at the same time improve the image quality of the optical lens
