Retro Reflective Technology
Retroreflection occurs when light rays are returned in the direction from which they came.
You can imagine someone working at the roadside. A car approaches with its headlights on. If the person was wearing a garment or e.g. a bag incorporating retroreflective material, a large amount of reflected light would be returned directly towards the original light source, i.e. the car headlights. This increases the visibility of the person to the driver of the car, and increases the driver's time to react accordingly and avoid a hazardous situation.
In the ORAFOL® product range, there are two different technologies used - the microprismatic technology and the glass bead technology. In this section you can learn how they differ.
Glass Bead Technology
In a glass bead system, light strikes the back surface of the bead and is returned to its source. Comparing this to the prismatic technology, light will strike each of the three prism surfacesin turn, before returning to its source. Because the microprism provides more reflective surface area than a glass bead, microprisms reflect up to 250 percent more light than glass beads.
Cube Corner Microprism Technology
ORAFOL can today call itself the original inventors of the microprismatic technology, and with more than 40 years of experience today we are the leaders of prismatic film manufacturing, providing products with the best possible visibiliyty in day- and nighttime, poor light and adverse weather conditions.
ORAFOL is the only manufacturer to offer the benefits of this superior technology consistently backed by years of experience, technical innovation and commitment to customer needs.
Prism technology works by refracting light from its inner surfaces. Light strikes each of the three surfaces of the microprism in turn, before returning to its source. The retroreflective efficiency is enhanced by the precise arrangement of the microprisms. The microprisms' economical use of surface area delivers the highest standard of reflection.
