Because of Epner’s critical role in the coating of optics, our polishing capability is frequently confused for optical polishing or lapping. Polishing done at Epner Technology is probably better characterized as buffing. This process has achieved surface roughness averaging less than 5 nano meters Ra (the equivalent of 5 nano meters = 50 angstroms).
We are able to polish most substrates down to mirror finishes. We work with diamond turning houses across the country to provide optical grade finishes on nickel prior to Laser Gold plating.
