METHOD FOR OBTAINING ULTRA-SMOOTH SURFACES OF OPTICAL ELEMENTS FROM ZINC SELENIDE
Annotation
The process of mechanical polishing of zinc selenide using a water-glycol suspension of ASM single crystal diamond and RDDM polycrystalline diamond is studied. Based on obtained results, a method for mechanical polishing of ZnSe is developed. The method is reported to provide the surface roughness of 0,227 nm, while deviation from planarity is less than one interference fringe, with a local error within 0,1 interference fringe.
