Maximum accuracy of optical polishing

The high precision of optical polishing can reach 0.65438 0.2 nm.

The principle of optical polishing is to achieve the purpose of precise polishing through the mechanical movement and chemical action between abrasive tool and glass. After unremitting exploration by hundreds of scientists, the highest accuracy can reach 0. 1 to 0.2 nm.

Optical polishing is a manufacturing technology widely used in the manufacturing process of high-precision mechanical and optical components. In this process, minimum defects and smooth micro-roughness values are needed.
