Glass Polishing Process
Double Side Final Polishing
Our double-side final polishing process maintains the flatness and parallelism characteristics achieved through the lapping process while creating a pristine surface with low roughness and surface defects. We can generally achieve scratch and dig specs as low as 5/2 and roughness to 5 Angstroms.
