Optimizing Refractive Index for Bright and Even Side Glow in Solid Core Object

Click For Summary
SUMMARY

The discussion focuses on optimizing the refractive index for a solid cylindrical object with a non-reflective core made of black rubber and a translucent or transparent plastic layer. The goal is to achieve a bright and even side glow when light is shone into the object, similar to side glow optical fiber. Key considerations include the selection of appropriate refractive indices for the outer layers to ensure effective light diffusion along the 20m length of the cylinder, even when bent.

PREREQUISITES
  • Understanding of refractive index and light propagation
  • Knowledge of materials science, specifically regarding plastics and rubber
  • Familiarity with optical fiber technology and side glow principles
  • Basic principles of light diffusion and scattering
NEXT STEPS
  • Research optimal refractive indices for various plastic materials
  • Explore the principles of light scattering in translucent materials
  • Investigate the design of side glow optical fibers for practical applications
  • Study the effects of bending on light transmission in cylindrical objects
USEFUL FOR

Engineers, materials scientists, and product designers interested in optical applications, particularly those focused on creating illuminated cylindrical objects with uniform light distribution.

Hi All,

I'm trying to create something which has a solid, cylindrical, non-reflective core (assume the core is made out of a black rubber similar to that of a car tyre for instance and 20m in length, but only 1cm in diameter), which has a translucent or transparent plastic layer (or several layers) wrapped (read: extruded) around this black, solid cylinder.

The purpose of the additional transparent or translucent layers is to ensure when a light is shone into the side of the previously black object, the whole object will glow. Similar to 'side glow optical fibre'.

The question is; what refractive index (or indices) do I need to aim for in the outer layer(s) to ensure the light glows brightly and spreads as evenly as possible along the length of the object longitudinally, even when the object is bent.

Thanks in advance.

Andrew
