Paper Abstract

This paper does research on the shrinkage deformation caused by photosensitive colophony solidification in manufacturing aspheric surface lens. With Finite Element Analysis, Orthogonal Experiment, and BP Neural Network methods, the relationship between the shrinkage deformation of aspheric lens and structure parameters is built up. With the mathematic model, the shrinkage compensable software for aspheric lens manufacturing is compiled to find out the original shape after the shrinkage deformed shape is given. As a result, the mould surface curve is easily obtained in accordance with the given aspheric lens shape.
