An Introduction to the Optics Manufacturing Process

manufacturing, the actual manufacturing process has, in many ways, remained unchanged. This paper serves as a basic overview of how a lens is manufactured from a 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.
