How does Solatube International, Inc. use optical technologies in its domes to capture and control the sunlight?

At the roof level, there is the main optical technology used in the domes of Solatube® Daylighting Systems: Raybender® 3000.
This patented daylight-capturing Fresnel lens integrates into the dome that provides consistent daylighting throughout the day. It accomplishes this by redirecting low-angle sunlight to increase early morning, late afternoon, and winter performance. The Raybender 3000 also rejects overpowering midday sunlight, especially in summer, to reduce glare and heat offering a more consistent daylighting experience.
