Research on the surface of a nonspherical lens with photosensitive colophony
2009
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.
