This patented technology consists of a series of Fresnel lenses moulded into the dome. They are located at critical locations inside the dome to redirect the daylight into the tube aperture at the steepest possible angle. This results in excellent light transfer even when the sun is low in the sky in the early morning, evening and during winter months.
This technology ensures the roof dome will actively harvest much more light than a clear dome or a flat glass panel throughout the day.
