ZEONEX and ZEONOR are ideal for LED applications requiring excellent optical properties, resistance to blue light source, and low moisture absorption. ZEONEX and ZEONOR resins can be utilized in many LED applications including:
• Collimating Lenses
• Cover Lenses
• Light Pipes
ZEONEX and ZEONOR resins offer:
• Glass-like Refractive Index
• Low Birefringence
• Low Water Absorption – more stable optical properties than PMMA.
• High transmission at 400nm

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.
ZEONEX COP resins have superior light transmission from 300-1200nm, as compared to PC and PMMA.
ZEONEX COP resins have 1/3 less birefringence as compared to polycarbonate(PC). The Photoelastic coefficient is ~5x10-13 cm 2/dyne.
ZEONEX has <0.01% water absorption - much less than PC and PMMA. ZEONEX parts are dimensionally stable and show minimal surface aberration in varying environmental conditions.
The above data are typical properties and should not be construed as specifications for the noted products.
