ZnSe Window Double Sided Lapping: Process, Parameters and Surface Figure Control
ZnSe window double sided lapping is the planar surface preparation step that brings a cut zinc selenide blank into the flatness, parallelism, and surface finish range required by CO₂ laser windows, beam splitters, and protective covers. It is not the final polish — but every downstream parameter, from coating uniformity to transmitted wavefront, depends on […]
