Pudi vacuum evaporation equipment PD-500C helps Sun Yat-sen University to achieve a new breakthrough in the application field of super-surface optical devices!

       Congratulations to Dr. Liu Yiqing of Sun Yat-sen University for publishing a research paper in CHIP International Journal with the help of Wuhan Pudi vacuum evaporation equipment PD-500C. In this paper, a super-surface based on germanium is proposed, which supports two different polarization BIC modes, showing its wide application potential in high-performance mid-infrared optical devices.
