当日，探索9年、经18个月加工“打磨”，一块直径4米、重达1.6吨的“大镜子”在中国科学院长春光学精密机械与物理研究所通过项目验收。这是国家重大科研装备研制项目“4米量级高精度碳化硅非球面反射镜集成制造系统”的最新成果，标志着我国大口径碳化硅非球面光学反射镜制造技术水平已经跻身国际先进行列。
On that same day, after 9 years of exploration and 18 months of processing, the “big mirror” with a diameter of 4 meters and a weight of 1.6 tons was approved by the Changchun Institute of Optics, Fine Mechanics and Physics of the Chinese Academy of Sciences. This is the latest achievement of the national major scientific research equipment development project "4-meter-scale high-precision silicon carbide aspheric mirror integrated manufacturing system", which indicates that China's large-diameter silicon carbide aspheric optical mirror manufacturing technology has now ranked best in the world.

CHANGCHUN, Aug. 22 (Xinhua) -- China has developed a high accuracy four-meter-aperture optical mirror, an important tool for deep space and astronomical observation.
Developed by Changchun Institute of Optics, Fine Mechanics, and Physics of the Chinese Academy of Sciences, the silicon carbide aspheric optical mirror measures 1.6 tonnes.
The silicon carbide used in production provides more stability to the surface of the mirror, allowing for greater accuracy at 20 nanometers.
In addition to the mirror, the research group also developed the manufacturing equipment used for the mirror's production and owns the IP rights for the equipment.
