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

[Fritzo130]

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

This problem is incompletely specified: what is the acceptance angle of the fiber? What is it made of?

14mm is a (ahem) large diameter for a fiber- is it a fiber bundle? or a light pipe? Perhaps a liquid light guide?

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.

It is PMMA plastic.

Hello Fritz,

It is possible to use a fresnel lens to transport light through a fiber optics cable. The focal point of the lens will act as a source of light for the fiber optics cable, allowing the light to travel through the cable and exit at the other end. However, there may be some heat loss due to the absorption and scattering of light within the fiber optics cable. The amount of light that exits the fiber optics cable will depend on the efficiency of the cable and the amount of light that is absorbed or scattered. This can vary depending on the quality and length of the cable. It is recommended to use high-quality fiber optics cables to minimize heat loss and maximize the amount of light that exits the cable. I hope this helps answer your question.
