研究了浮子抛光技术，以确定其在光学材料上产生超光滑表面的适用性，产生<2 a rms的粗糙度。尝试抛光六种不同的材料，包括熔融石英，Zerodur和蓝宝石。熔融石英、Zerodur和康宁实验玻璃陶瓷材料的表面粗糙度较低，而o型切割单晶蓝宝石的表面粗糙度<1 a rms。据推测，在cerit和ULE石英上也可以获得类似的表面光洁度，由于样品安装和机器配置之间的不匹配，在这组实验中不能得到令人满意的抛光。
The float-polishing technique has been studied to determine its suitability for producing supersmooth surfaces on optical materials, yielding a roughness of <2 A rms. An attempt was made to polish six different materials including fused quartz, Zerodur, and sapphire. The low surface roughness was achieved on fused quartz, Zerodur, and Corning experimental glass-ceramic materials, and a surface roughness of <1 A rms was obtained on O-cut single-crystal sapphire. Presumably, similar surface finishes can also be obtained on CerVit and ULE quartz, which could not be polished satisfactorily in this set of experiments because of a mismatch between sample mounting and machine configuration.
