摘要
随着消费电子行业的增长和人们对轻便易携带的高性能产品的需求,非球面玻璃透镜的需求量持续增长。与传统冷加工方法相比,模压成形技术因具有低成本、批量生产的能力而成为一种更有前途的加工方法,尤其适合中小口径非球面透镜的生产。非球面玻璃透镜的模压成形技术是一项涉及玻璃材料、超精密模芯加工、镀膜、模压成形工艺及成仿真等诸多领域的综合技术。因此,有必要对其中影响成形质量的关键技术进行系统分析和深入研究,探讨模压成形技术现状和存在的问题。对光学玻璃的物理化学性质、主要构成成分、粘弹性、低熔点及环保的发展趋势、预形体的选择进行综合分析;对模芯材料的开发、非球面模芯的单点金刚石车削技术、纳米磨削技术、超精密研抛技术、复合加工技术、镀膜材料、镀膜技术做了详细介绍;阐述模压成形技术及仿真技术的研究现状及最新进展;并对未来发展趋势进行预测与展望。
The growth of the consumer electronics industry and a desire for light weight, compact, portable and high performance products has led to an increasing demand for aspherical glass lens. Glass lens molding offers a promising approach for large volume, cost effective production of precision micro aspherical glass lens which is difficult to make using conventional abrasive lens fabrication techniques. The glass lens molding technology is a comprehensive processing strategy and keeps close relations with such fields as optical design, glass materials, ultra-precision mold process, coating, glass molding process, molding simulation and so on. Therefore, it is necessary to make systematic analysis and intensive review on these key technologies which influence the molding quality. The retrospection of the development history and status of glass molding process is presented. The characteristic of optical glass, major components, low melting point and environmental trends are analyzed. The development of mold materials, nano-grinding, ultra-precision polishing, coating materials and coating technology are analyzed. Molding technology status and simulation techniques are analyzed. The development trend is pointed out.
