Spherical mirrors have reflecting surfaces forming part of a precise sphere and are mainly concave or convex. Concave mirrors converge parallel rays to a real focus for solar cookers, astronomical telescopes, and searchlights. Convex mirrors diverge light and form upright, reduced virtual images to widen the field, as in vehicle rear-view and road wide-angle mirrors. Spherical mirrors are simple and have no chromatic aberration, but spherical aberration often requires aspheric optimization in precision systems. Dongkeda offers uncoated and reflective-coated mirrors, including standard protected aluminum, protected UV-reflecting aluminum, and protected gold. Metallic mirrors generally meet optical instrument requirements; multilayer dielectric coatings provide higher reflectance and lower absorption loss where required.
