高效率反射光栅筱晓（上海）光子技术有限公司

产品描述

LightSmyth使用电信级偏振分集光学设计和激光频率稳定技术生产高效率反射光栅。采用投影光刻和反应性离子蚀刻技术在硅单晶基底上金属化，以实现单极化的高效性能。每个光栅均设计为母光栅，而不是复制光栅，达到低散射光和持久性能目标。规模化晶圆成本效益的制造为客户实现非常高的有竞争力价格。

更重要的是，相比传统的商业复制的全息光栅和机械排除光栅，减少散射光达到100X，达到最佳信噪比和低信道串扰。点击http://www.lightsmyth.com/products/premium_reflection_gratings/images/low_scatter.gif查看比较。
