retroheijastavien
Retroheijastavien is a Finnish term referring to retroreflective materials. These are materials designed to reflect light back towards its source, making them appear brighter than ordinary reflective materials. This property is achieved through the use of small, transparent beads or tiny prisms embedded in a binder. When light strikes these elements, it is refracted and reflected back along a path parallel to the incoming light, regardless of the angle of incidence.
The primary application of retroreflective materials is in enhancing visibility in low-light conditions. This is crucial
Different types of retroreflective materials exist, varying in their structure and performance. Glass beads, for instance,
