High accuracy kdp crystal optics is now considered as one of optics that is the most difficult to be processed for its series of disadvantageous characteristics to optics processing such as anisotropy, soft nature, easy to deliquesce, high brittleness, sensitive to temperature change, easy to crack and so on. therefore the long machining period, low percent of pass and astaticism quality has become the bottleneck of icf technology, and the surface quality control of kdp crystal processing has become the key problem to be solved in the research of icf in our country
Kdp晶體零件是目前公認的最難加工的光學零件之一，因為kdp晶體具有各向異性、質軟、易潮解、脆性高、對溫度變化敏感和易開裂等不利於光學加工的特點，所以加工周期長、合格率低、質量不穩定成為慣性約束聚變技術的瓶頸， kdp晶體超精密加工表面質量控制問題已經成為我國慣性約束聚變研究中亟待解決的關鍵問題。 -
