    How Effective Is a Fresnel Lens in Transporting Light Through Fiber Optics?

    The fresnel lens would have its focal point hitting normal to the end of the fiber optic cable. All I know about the material of the fiber optic cable is that is a "poly-rubber plastic". It is a single, solid, 14mm fiber optic end glow cable that is PVC jacketed.

    How Effective Is a Fresnel Lens in Transporting Light Through Fiber Optics?

    Hello, I have a 12x12" fresnel lens and I want to place a 14mm diameter fiber optics cable at the focal point to transport the light ~2.5 ft. Would there be any heat loss? And what percentage of the light would exit the fiber optics? Thanks, Fritz Laun

    Calculating Heat Transfer for a Water-Cooled Fresnel Lens System

    Hello, everyone, I have a question on how to calculate the heat transfer and change in temperature for a project I am working on. It consists simply of a cooling water block (that you would find on a tec cooler etc), a fresnel lens, and a pump. The fresnel lens focuses the light onto...

    Fresnel Lens Array - Focal Point Question

    Hello, all, I am using 9 fresnel lenses (~1x1' per lens) and 9 water blocks for a solar water heater. Each fresnel lens is positioned so that a water block below is heated. A pump is used to pump the water through the system. However, I have one question... I have all of my fresnel...
