The reflection on the glass surfaces cause to declining the performance of optical lens. In the previous study, we successfully fabricated the antireflection structures (ARSs) on the convex lens. However, this process can’t be applied the more complex shapes like the aspheric lens. Therefore, the purpose of this study is fabricating the ARSs on the aspheric lens. We have successfully fabricated the ARSs on the aspheric-convex lens by alignment with the aspheric-concave lens which was fabricated the ARSs. Furthermore, we suppressed the reflectance about 0.4%, and this process can be expected to improve the performance of the optical lens.
