High Refractive Index Optical Resins for Lenses

Lens Resins

ACW offers high refractive index (high RI) materials that give cured resins with RI in the range 1.52 to 1.60 @ 589 nm.  The cured resins are hard, optically clear materials suitable for lens applications including Wafer-Level-Optics lens for cameras in mobile phones.  They have high Tg, are heat stable, and are compatible with solder reflow.

APPLICATIONS:  The ACW L series resins are designed for UV nanoimprint lithography (NIL) and step-and-flash imprint lithography (SFIL) or UV-embossing for making Wafer-Level-Optics lens for image sensor modules, optical lenses, hybrid lenses for mobile phone applications.
