今天光学眼镜发展的驱动市场是多媒体应用，如数字投影、数码摄像机和DVD播放器，以及数码摄影市场的数码数码相机、单反相机和照相手机。随着组件进一步小型化的趋势和光效的提高，以及环保组件的大量使用，这些市场对具有定制性能的光学玻璃产生了很高的需求。这些需求导致了诸如在蓝色区域具有高透射率的高折射率玻璃类型、具有低色散特性的玻璃、具有反常部分色散的玻璃和具有低应力光学常数的玻璃的改进和发展。熔制技术和玻璃成分的改进，使经济地生产更困难的玻璃成为可能。低玻璃温度（Tg）的玻璃预制体具有优异的表面质量，适合通过精密成型工艺批量生产非球面透镜。本报告将概述肖特光学玻璃领域的最新发展。
Today's driving markets for the development of optical glasses are multimedia applications, like digital projection, digital camcorders and DVD players, and the digital photography market with DSC, DSLR and camera phones. With tendencies of further component miniaturization with increasing light efficiency at the same time and the use of environmental friendly components in big amounts these markets generate high demands of optical glasses with tailored properties. These demands lead to improvement and development of e.g. high refractive index glass types with a high transmission in the blue region, glasses with low dispersion characteristics, glasses with anomalous partial dispersion and glasses with low stress optical constants. Improvement in melting technology and glass composition makes it possible to economically produce even difficult glasses. Preforms with excellent surface quality from glasses with low glass temperature (Tg) are suitable for the mass production of aspherical lenses by precision molding processes. This presentation will give an overview of the new developments in the field of optical glass at SCHOTT.
