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.
