Diffuse reflectors are widely used in optical laboratories, remote sensing and other fields involving optical measurement. So far, large reflectors (larger than 500 x 500mm in size) are made by applying a layer of barium sulfate white paint on the surface. The limitation of this method is that the surface needs to be repainted (depending on the laboratory or environmental conditions), and the advantage is the initial cost of spraying.

Competitive reflectors have excellent reflectivity performance, but due to the use of sintered polytetrafluoroethylene (PTFE) as a monolithic material, they are heavy, fragile and expensive. Using Zenith LiteTM technology, we use a new technology, the Zenith Polymer? Diffuser attached to the substrate interlayer on light. The performance and strength of the reflector are maintained at the same level as other polymer materials, but they have great advantages in weight and cost.
