A Reflective Layer is a component in various technologies that enhances the performance of materials by reflecting light or other forms of energy. This layer is often used in applications like solar panels, where it helps to maximize energy absorption by directing more sunlight onto the active surfaces. In the context of optical devices, a reflective layer can improve visibility and clarity by reducing glare. It is commonly found in products such as mirrors and lenses, where it serves to enhance the quality of the reflected image or light transmission, making them more efficient and effective in their use.
