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

Click For Summary
SUMMARY

The discussion centers on the use of a 12x12" Fresnel lens to transport light through a 14mm diameter fiber optic cable, specifically a single, solid, end-glow cable made of PMMA plastic with a PVC jacket. Key concerns include potential heat loss and the percentage of light exiting the fiber optics. The effectiveness of this setup depends on the acceptance angle of the fiber and the specific characteristics of the fiber optic material.

PREREQUISITES
  • Understanding of Fresnel lens optics
  • Knowledge of fiber optic cable types, specifically PMMA and PVC materials
  • Familiarity with light transmission principles
  • Basic concepts of acceptance angles in fiber optics
NEXT STEPS
  • Research the optical properties of Fresnel lenses
  • Learn about the acceptance angle and its impact on light transmission in fiber optics
  • Explore the thermal properties of PMMA plastic in optical applications
  • Investigate the differences between fiber bundles, light pipes, and liquid light guides
USEFUL FOR

Optical engineers, fiber optic technicians, and anyone involved in light transmission technologies will benefit from this discussion.

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.
