World's Foremost Optical Polymer for Precision-Molded Optics

Glass-Like Optical Properties

ZEONEX Cyclo Olefin Polymer (COP) optical polymers exhibit glass-like transparency from UVA through NIR wavelengths. With a refractive index of 1.53 and ABBE number of 56, ZEONEX Cyclo Olefin Polymer (COP) combines the optical characteristics of glass with the design freedom of a molded plastic.

Zeonex Cyclo Olefin Polymer: high optical, glasslike transparency compared to Cyclo Olefin Copolymer and other plastics.



Cyclo Olefin Polymer: glasslike optical properties, high refractive index, high Abbe number. Low dispersion & birefringence.

Low Birefringence

ZEONEX Cyclo Olefin Polymer (COP) achieves very low total birefringence by combining low intrinsic birefringence with an ultra-low photoelastic constant for excellent stress birefringence performance. Compared with other polymers, the higher molding temperature capability of Cyclo Olefin Polymer (COP) also promotes improved birefringence by allowing for reduced molecular orientation during molding.

Low Moisture/High Temperature Environmental Stability

ZEONEX Cyclo Olefin Polymer (COP) has <0.01% water absorption – significantly less than polycarbonate (PC) and acrylic polymethyl methacrylate (PMMA). Lenses made with ZEONEX Cyclo Olefin Polymer (COP) are dimensionally stable, and show minimal change of optical properties following exposure to varying humidity environments.

ZEONEX Cyclo Olefin Polymer: precise dimensional, optical stability under high humidity environments than polycarbonate/acrylic.



Blue and NIR Laser Capability

ZEONEX Cyclo Olefin Polymer (COP) optical grades are engineered to meet requirements of high-performance and specialty applications. Certain grades of ZEONEX Cyclo Olefin Polymer (COP) offer good resistance to long-term exposure to blue light and NIR wavelengths, such as those found in blue laser optical pick-up systems and 3D position sensing.


High Molding Precision

With mobile device camera pixel size steadily increasing, producing dimensionally accurate and defect-free microlenses is more important than ever. ZEONEX Cyclo Olefin Polymer (COP) exhibits extremely high molding transcription, which allows precise control of part dimension and flatness while maintaining ultra-low peak-to-valley (PV) ratios on the surfaces of lenses and prisms. High-flow grades of ZEONEX Cyclo Olefin Polymer (COP) extend the ability of cyclo olefin polymer to be molded into very thin, high-curvature lenses with lowered risk of knit-line formation. Nanoscale surface features and gradients are no match for the high-resolution molding capability of ZEONEX Cyclo Olefin Polymer (COP).

ZEONEX Cyclo Olefin Polymer molding capability: High degree of flatness and low peak to valley - precision mold optics.

ZEONEX Cyclo Olefin Polymer molding capability: High degree of flatness and low peak to valley - precision mold optics.

Cyclo Olefin Polymer - higher microstructure capabilities for molding defractive optics and lens than Cyclo Olefin Copolymer
