Optical Grade Lens Module Polished Cerium Oxide Polishing Powder

In the manufacturing industry of optical lenses, controlling the preparation process is the key to producing optical lenses. After being finely ground with grinding solution, the surface of optical lenses still has a crack layer with a thickness of about 2-3m. The method to eliminate this crack layer is polishing.The purpose of this product is to provide a safe, non-toxic, good polishing effect, and scratch reducing polishing powder for optical lenses
