What are highly reflective coatings?

Originally high-reflective coatings were used to reduce light from lasers and other light sources while reflecting them. Therefore, technicians recommend that laser machines have highly reflective coating materials because the scatter of the laser beam can cause injury if the laser is pointed directly at the patient, for example, during laser eye surgery. In short, HR coatings are essential for laser machine effectiveness so that less laser power is used during application.
