Lens Resins

Optically clear, high refractive index and ultra hard UV-curable resins suitable for UV nanoimprint lithography (NIL) or step-and-flash imprint lithography (SFIL) for wafer-level-optic lens or high resolution lens and LED encapsulations.  The resins have refractive indices from 1.52 to 1.60 at 589 nm.  ACW lens resins are suitable for high throughput imprint technology, are stable to solder reflow at 260 °C, and are non-yellowing in harsh environment conditions of high heat and humidity.  ACW lens resins are used for fabrication of wafer-level camera image sensor modules for mobile phone camera lens applications.
