The Excel-Ray process can make PMMA fibers diffuse along a chosen length. Rather than using the light at the end of the fiber, it is here distributed homogeneously along its length. Our treament allows them to reach a high output level flow/inflow of about 80%.

Light that an optical fiber can diffuse is necessarily limited by the flow which can enter into its section.
To increase the flow returned we group fibers into cables.

By applying the Excel-Ray method to PMMA bar we can extract light through its surface.

The Ice Corian is a material that lets light go through and diffuses it.
Lighting by transparency requires light sources behind panels, and thus maintenance.
DuPont de Nemours Geneva contacted Excel-Ray to look for a solution.

In addition to conventional light sources such as halogen iodide generators, we use more and more LEDs to power our diffusing optical fibers.
