calcium fluoride 氟化鈣,螢石。

calcium hydroxide

The gravity analysis is carried out especially for the synthetic fused silica and calcium fluoride used in 193nm lithographic objective as well as the optical elements with structural sizes of ( 200mm ~ ( 300mm . large numbers of analysis data for surface shape error are obtained by using algor finite element analysis software . then these data are plotted into curves and comparison analysis will be carried out , finally the measures and schemes for reducing gravity deformation are proposed 因此,本論文重點對大口徑光學系統在高精度光學鏡頭裝校中,因重力變形進行了詳細的分析研究,特別針對193nm光刻物鏡系統所使用的材料sytheticfusedsilica和caleiumfluoride以及用到的結構尺寸200mm ~ 300mm光學零件進行了重力變形分析,使用algor有限元分析軟件獲得了大量的面形誤差分析數據,然后將這些數據繪成曲線進行對比分析,最后提出了減小重力變形的措施與方案,并進行了實驗,驗證了分析結果是正確的,減小重力變形的方法是有效的。
