Book excerpt: The use of plastic optics instead of glass offers a number of advantages. Most importantly, it is far less expensive, and therefore opens a huge potential for mass production. It also offers the opportunity to use unique element configuration. This book gives a coherent overview over the current status of injection molded optics describing in detail all aspects of plastic optics, from design issues to production technology and quality control. The focus is firmly set on practical applications, making this an indispensable information source for all those working in optics research and development. The contributors, each one a leading expert in his chosen discipline, possess either a background in industry or close relations to the industry, thus bringing in an ample amount of practical experience.
