Abstract: In order to realize high precision measurement of large aperture convex aspheric surface with small aperture Hindle lens, a new Hindle testing method of convex aspheric double-lens with zero-focal power is proposed. The shortcomings of traditional Hindle test are solved effectively by adding correction lens with zero-focal power. The design and analysis of the convex aspheric surface with the aperture of 180 mm,radius of 380 mm and eccentric ratio of 2.8 are carried out. The residual wave aberration curves of the system are given respectively by different focal power distribution and changing the distance between two lenses with zero-focal power. A better system residual wave aberration of 0.0006λ is obtained, and the feasibility of the method is verified.
