 company that is made of millions of glass beads affixed to the surface. Each glass bead is covered with a metallic reflective layer on half of its surface (the "back" half) and this, combined with the spherical nature of the glass beads gives the materials their reflective properties.

A retroreflector is a device or surface that Reflection light back to its source with a minimum scattering of light. An electromagnetic wave front is reflected back along a vector that is parallel to but opposite in direction from the wave's source....
 optical properties of the glass beads, collecting light from a very wide range of angles of incidence and reflecting the collected light back along a single focused line of sight.

 optical properties of the glass beads, collecting light from a very wide range of angles of incidence and reflecting the collected light back along a single focused line of sight. When viewing the Scotchlite surface across this line of sight, the surface gives the appearance of reflecting far more light than a normal diffuse reflection. It is used for screens
