Synthetic Gypsum-Based Plaster for Production of Multiple Optical Glass Lenses

To improve the efficiency of lens blocking for grinding and polishing, plaster use was studied in the work herein reported.The dimensional stability, low thermal expansion, shapability, and cost-effectiveness of plaster can contribute to the production of high-quality optical lenses. These results foster advancements in optical manufacturing, enhancing the simultaneous processing of multiple lenses or prisms.
