The reflector (10) includes a substrate (16) and a plurality of intermediate layers which include at least one bonding layer (18) disposed upon the substrate and a metallic reflectance layer (20) disposed upon the bonding layer. The bonding layer includes a first dielectric layer (22), such as aluminum oxide (Al2O3), for bonding or adhering the metallic reflectance layer to the substrate. The reflectance layer is preferably comprised of a silver material which reflects a high percentage of the incident light. In addition, the reflector can include a protective layer (26), such as a layer of Leybold Mark 3 material, for protecting the underlying bonding and reflectance layers, such as from tarnishing and other environmental degradation. As a result, the reflector provides a relatively high level of reflectance which does not degrade over time since the reflectance layer remains tightly adhered to the substrate and since the reflector is protected from tarnishing. In addition, the reflector can be curved in order to further focus the reflected light. |
