An Introduction to the Optics Manufacturing Process

is loose abrasive grinding. This involves using various grit sizes mixed with water (this mixture is called a slurry) to remove glass. The larger the grit size, the more glass is removed, resulting in a faster removal rate. However, a rougher surface will be produced. Therefore, generating begins with large grit sizes of up to 100-200µm and
