Paper Abstract

Now the design and manufacture of large aperture optical lens are increasing emphasis on the influence of the gravity deformation of optical system. A compensation method of large aperture optical lens for gravity deformation is presented in this paper. The method analyses in advance and predicts the gravity deformation to compensate it in the processing stage. Taking the difficulties of machining into consideration, the spherical compensation mode is adopted and the compensation accuracy is given. The wave aberrations caused by gravity deformation before and after the compensation are compared and it proves that this method can effectively reduce the influence of gravity deformation though advance compensation.
