This work shows a method to recover the shape of the precision glass molding surface via null-screen test. For the validation of the proposed method, we analyzed the ACL25416U condenser lens fabricated by Thorlabs. The results show that the conic constant, the radius of curvature and the aspheric deformation coefficients can be retrieved with good accuracy.
