Camera lens elements manufacturing process
WebSo the modern lens designer may work on "lenses" that are a long way from your bifocals or pocket 35 mm camera (although the compact lens in a pocket camera can represent some clever design and cost-effective engineering). If a system uses light in some way (including any system that uses laser beams), lens design is almost certainly involved. WebFeb 9, 2008 · Once the lens passes the simulation test, a prototype lens is produced to determine the actual performance. Camera Lens - The Manufacturing Process Optical …
