A concave mirror is a reflective optical element possessing unique optical characteristics and broad applicability. It exhibits light-converging capability: when parallel incident rays strike its surface, they reflect and converge at a single point—the focal point. Depending on the object’s position relative to the mirror, it can produce either an enlarged virtual image or an enlarged real image. Concave mirrors typically feature high reflectivity, enabling efficient light reflection with minimal loss. Manufacturing such mirrors demands precision—careful machining and polishing yield components with precisely controlled curvature and dimensions, tailored to diverse application requirements.
