GORE™ DRP® Diffuse Reflector Material
GORE™ DRP® is the world’s most diffuse reflective material, maximizing the uniformity of light it reflects. The material absorbs no measurable light energy, and is resistant to heat and ultraviolet.
In both visual light and ultraviolet (UV) light, this material is highly reflective. It is useful for many applications, including display backlighting, UV-disinfection, and UV-curing.

Diffuse vs. Spectral Lighting
There are two kinds of reflectance, diffuse and spectral. In spectral reflection, the angle of incidence equals the angle of reflection. Therefore, in the reflector of a recessed light fixture, for example, light may reflect many times before it issues from the opening of the fixture. Each time light reflects, however, it loses a portion of its energy--its illumination. A poor reflector can absorb a significant amount of energy in this way before the light emerges from the fixture.
The GORE™ DRP® Diffused Reflector material is highly reflective, with light being reflected at multiple angles. The reflectance can be termed as lambertian because light falling on the surface of the material is scattered such that the apparent brightness at the surface is the same regardless of the angle of view.
Reflectance increases somewhat with thickness, but even at 1.0 mm, reflectance is 98.5% with no measurable absorption of light energy. The product is equivalently reflective from the near-infrared (about 240 nm) through the visible spectrum to the ultraviolet (about 2500nm).
