SmartGel is a novel optical couplant that helps LEDs shine brighter, last longer and survive extreme environments.

SmartGel is a breakthrough in LED encapsulation providing a new alternative to optical-grade epoxy resins.

Custom designed to match the packaging system of any LEDs, SmartGel increases lumen output, extends lumen life and survives demanding operating conditions better than an epoxy.

SmartGel consists of a low-viscosity optical fluid and chemically active thickening agent.

The uncured components fill the gap between the LED and the lens, cure in place and become a stable, crystal clear, long-life viscoelastic gel.

SmartGels are formulated to match precisely the refractive index of a lens and can be optimised for specific wavelengths.

SmartGel is nonyellowing under typical conditions and keeps LEDs brighter for their functional life.

Unlike epoxies, which can fracture or stress leading to delamination with thermal expansion and contraction, SmartGels are mechanically stable and viscoelastic, allowing relief of stress.

This means that LEDs can last longer.

SmartGel is also production friendly allowing the user to determine cure and set times.
