PURPOSE:To widen the selection width of the kinds and polymerization degree of a light reactive material and a high polymer for binding which are used to prepare a film thickness distributed film by incorporating a solvent in a film which contains the light reactive material and removing the solvent from the film simultaneously with or after photoirradiation. CONSTITUTION:This method is applicable to the manufacture of a plastic microlens, a plastic waveguide, a hologram, etc., and then film 11 which contains the light reactive material and solvent is formed on a substrate 10. This film 11 is irradiated locally with light 13 by using a mask 12, the film shape is varied to form a lens 14, etc., and the solvent is removed simultaneously with or after the photoirradiation. While the solvent is present in the film, the light reactive materials is diffused to form a curved surface by surface tension. Consequently, the light reactive material such as cholesterol cinnamate and the binding high polymer which can not be used when the solvent is not used can be used by incorporating the solvent. |
