2016年11月12日,由中科院长春光机所承担的国家重大科研装备研制项目“大型高精度衍射光栅刻划系统的研制”顺利通过验收,由它刻划的世界最大面积中阶梯光栅在长春诞生。由中科院组织的验收专家组表示,光栅刻划系统和光栅都达到了项目实施方案的技术指标,该项成果填补了国内空白,技术己达国际领先水平。光栅是一种具有纳米精度周期性微结构的精密光学元件。它看似陌生,却与我们的生活息息相关。作为核心色散单元器件,光栅在光谱学、天文学、激光器、光通讯、信息存储、新能源等诸多领域中具有重要应用。而光栅刻
November 12, 2016, the Chinese Academy of Sciences Changchun Institute of light major national research and equipment development project “Large-scale high-precision diffraction grating scoring system ” passed the inspection, it is the world’s largest scored by the middle of the ladder grating In Changchun was born. The acceptance expert group organized by the Chinese Academy of Sciences said that the grating scoring system and the grating all achieved the technical specifications of the project implementation plan. This achievement has filled the domestic blank and the technology has reached the international advanced level. Gratings are precision optical components with nanometer-precision periodic microstructures. It looks strange, but it is closely related to our life. As the core dispersion unit device, grating in the spectroscopy, astronomy, laser, optical communications, information storage, new energy and many other fields have important applications. The grating engraved
