Fabrication and testing of optical components - Wikipedia

Optical fabrication and testing spans an enormous range of manufacturing procedures and optical test configurations.. The manufacture of a conventional spherical lens typically begins with the generation of the optic's rough shape by grinding a glass blank. This can be done, for example, with ring tools. Next, the lens surface is polished to its final form.
