An Introduction to the Optics Manufacturing Process

Oct 31, 2008The typical life of a lens begins as a glass blank. This is the basic material that the final lens will be made from and can be ordered in many shapes and sizes (Figure 1). These are usually ordered from an optical glass company. Major glass companies include Schott, Ohara, and Hoya.
