Low power, high reflectivity broadband metal mirror enhanced for visible; 450-650 nm. These aluminum mirrors are enhanced with a high quality multilayer dielectric coating to both protect the aluminum coating and increase reflectivity at mid-visible wavelengths. Peak reflectance in the visible is > 93%, while average reflectivity is > 95%. They are as durable and reliable as protected aluminum mirrors.
