How does a lens go through the manufacturing process?
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 optic is finished to specification.
What is the process of polishing a lens?
After the lens is generated and fine ground, it undergoes polishing. Depending on how precise the generation is, the lens may go through several stages of polishing.
