WEB EXCLUSIVE: Japan’s Zeon Corp. (U.S. office in Louisville, Ky.) has developed a high-transparency cyclo-olefin polymer (COP) for use in smartphone and tablet-computer camera lenses, which have smaller and thinner camera modules. These smaller modules require camera lenses that are not only thinner, but also capable of producing the high-image quality required for optimum display on larger smartphones and tablet screens.
New Zeonex KR6R is designed to meet these market requirements with easy moldability that is said to result in thinner lenses with low birefringence. The material reportedly makes it possible to reduce lens thickness by approximately 50% compared with conventional lenses. Zeonex COP also boasts extremely low outgassing and resulting defects on finished parts.
