blank. A lens is typically ordered from a glass company in a form called a glass blank. From there, the lens goes through generation where the rough shape is ground into the blank. A lens is then blocked and undergoes further grinding to improve the surface and shape. Polishing is the final fine grinding stage where the surface and shape of the ...

The assumed mechanism of the grinding process assisted by the chemical action of the CeO 2 covered diamond wheel is shown in Fig. 1.While cerium exists as Ce 4+ inside of a CeO 2 abrasive, it is ionized to Ce 3+ at the surface due to oxygen deficiency. When the CeO 2 abrasive contacts the optical glass surface, electrons formed by the oxidation of Ce 3+ on the surface of the …
