High performance optical materials cyclo olefin polymer ZEONEX

ZEON CORPORATION developed innovative optical plastic Cyclo Olefin Polymer (COP), ZEONEX ^(R) with own technology in 1990 then started commercial production of ZEONEX^(R) for optical applications with its very unique properties such as high light transmission, low birefringence, low water absorption, and high glass-transition temperature etc. ZEONEX^(R) exhibits outstanding optical performance even under high humidity and temperature conditions. In order to meet increasing requirements of optical market, ZEON CORPORATION newly developed ZEONEX^(R)F52R which has high glass-transition temperature 156 deg. C and shows the feature of very low focal length change after high-temperature and high-humidity test.
