An Introduction to the Optics Manufacturing Process

2008-10-31  Molded optics are a common way to produce small lenses in high volume. A molded optic starts as a preform, which is a ball or disc that has already been polished to very high quality. It is then shaped in a mold at high temperatures. The overview of this process can be seen in Figure 9. Figure 9: Overview of the Molding Process (Schott)
