Optical Component and Lens Applications
ZEONEX has earned high marks for low moisture absorption, good transparency and high precision molding. ZEONEX resins can be utilized in many applications including:
• Camera Lenses
• Prisms
• Mirrors
• F-Theta Lenses
• Pick-up Lenses
• Projections Lenses
ZEONEX resins offer:
• High Transparency
• Low Fluorescence
• Low Birefringence
• Low Water Absorption – more stable optical properties than PMMA.
• High Heat Resistance
• Chemical Resistance
For blue-laser applications, 340R has been specially designed.

EXCELLENT MOLDABILITY
ZEONEX can be molded for complex lenses and prisms requiring precise features, fast cycle times, and uniform optical properties.
ZEONEX allows for more precise molding than with PC and other plastics.
REFRACTIVE INDEX/ABBE NUMBER
ZEONEX COP has a refractive index similar to glass. The refractive index is significantly lower than Polycarbonate (PC). The ABBE number is similar to PMMA.
HEAT CYCLE TEST
ZEONEX COP has more stable optical properties after heat and humidity exposure than does PMMA.
TRANSMITTANCE IN NEAR-INFRARED AREA
ZEONEX COP resins have excellent light transmission from ~300nm to ~1200nm. The light transmission is reduced above 1200nm.
LIGHT TRANSMITTANCE
ZEONEX COP resins have superior light transmission from 300-1200nm, as compared to PC and PMMA.
HIGH HEAT RESISTANCE
ZEONEX COP resins have higher heat resistance than common PMMA, PP, and PET resins. This enables ZEONEX to be utilized in optical applications where the part will be exposed to extreme heat and/or humidity.
LOW WATER ABSORPTION
ZEONEX has <0.01% water absorption - much less than PC and PMMA. ZEONEX parts are dimensionally stable and show minimal spherical and coma aberration of lenses after exposure to humid environments.
