Achieving a vivid and clear visual experience

With its low birefringence and high spectral transmittance, AZP™ provides a vivid and clear visual experience. Furthermore, its excellent light resistance ensures that it maintains consistent quality even under prolonged exposure to sunlight and ultraviolet rays.

Suppression of ghosting and flaring

When optical components are made from resin, birefringence tends to cause image degradation and blurring, which reduce visibility. Leveraging advanced molecular design and unique polymerization technology to control birefringence at the molecular level, we have reduced the birefringence of AZP™ to nearly zero. This effectively suppresses ghosting and flaring, delivering a vivid and clear visual experience.

Vivid visual experience

As AR and VR applications rapidly expand, users seek more immersive experience. Achieving deep immersion requires images with high resolution and vivid colors. With high spectral transmittance similar to cyclic olefin polymer (COP) and cyclic olefin copolymer (COC), AZP™ delivers excellent color reproduction across all wavelengths in the visible spectrum. In addition to AR and VR devices, AZP™ is well suited to automotive heads-up displays (HUD) and center information displays (CID), where visibility is crucial.

Durable performance

Devices such as automotive head-up displays (HUD) and center information displays (CID) need to endure prolonged exposure to sunlight. AZP™ offers superior light resistance compared to other resins, and remains clear and sharp without yellowing even after long-term exposure to ultraviolet rays.

AZP™ has a smaller yellowness index (YI) change than cyclic olefin polymer (COP) after light resistance test by SWOM (without rain) for 1,000 hours. The graph shows typical test results, not guaranteed values.

Reasons to Choose AZP™

Make products smaller and lighter

Although the birefringence of AZP™ is comparable to glass, its specific gravity is less than half. This allows products to be made smaller and lighter.
