What is the final finish described after polishing of the backside?

Explanation:
Polishing aims to remove microscopic irregularities so the surface becomes optically smooth. After polishing the backside, the final finish should be perfectly smooth and clear, allowing light to pass through with minimal scattering. Seeing through the surface indicates high optical clarity and a low roughness. If there were any remaining roughness, light would scatter, making the surface appear hazy or dull; a protective coating is a separate step and isn’t the inherent result of polishing.
