At the roof level, there are two main optical technologies used in the domes of Solatube® Daylighting Systems: LightTracker™ and Raybender® 3000. The LightTracker Reflector captures low-angle sunlight, specifically in early morning, late day and winter, that would otherwise pass through the dome, and redirects it into the tube. In this way, the system collects the maximum amount of light possible throughout the day and year. This, in turn, yields greater light output in the interior space.
Raybender 3000 Technology is a patented daylight-capturing Fresnel lens integrated 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. It also rejects overpowering midday sunlight, especially in summer, to reduce glare and heat offering a more consistent daylighting experience.
