What is a concave mirror, or focusing mirror? Concave mirrors are commonly used where light concentration is required. Their inward-curved reflecting surface focuses light at an internal focal point. Parallel incident rays converge after reflection at a focus in front of the mirror. A source at the focus produces a parallel reflected beam. Imaging varies with object distance. Concave mirrors have optical properties similar to lenses and can play equivalent roles, particularly in optical information processing. Applications include microscopes, astronomical telescopes, dental mirrors, imaging systems, and lasers. Changchun Longze Precision Optics Co., Ltd. manufactures precision optics, offering custom concave mirrors and valuable advice based on years of production and supply experience.
