| titleOfInvention | Fresnel lens manufacturing method |
| abstract | (57) [Summary] [Structure] A heat-polymerizable liquid is obtained by injecting a heat-polymerizable liquid resin between a master having a Fresnel lens surface and an optically transparent substrate and heating. The Fresnel lens surface is formed on the base material by polymerizing and curing the resin, and integrated. [Effect] Shortening the preheating time of the thermoplastic resin sheet by the pressing method and the cooling time of the mold, elimination of mold release defects due to shrinkage during cooling of the thermoplastic resin sheet, the mold surface being exposed to high temperature To eliminate the occurrence of defects on the lens surface due to the oxidation of the 2P, to eliminate the decrease in transparency in the 2P method, to shorten the polymerization and curing time in the cast method, to reduce the shrinkage during polymerization and to make the plate thickness uniform. It is excellent in measurement, quality and productivity and has a great effect. |
