BelOMO or Belorusskoe Optiko-Mechanichesckoye Obyedinenie (Беломо or Белорусское оптико-механическое объединение, Belarus Optical & Mechanical Association) was founded in Minsk in 1971 in Byelorussian SSR, Soviet Union, now Belarus. The main factory is the Minskiy Mechanichesckiy Zavod imeni S.I. Vavilova, opened in Minsk 1957 and named after the Soviet physicist Sergey Ivanovich Vavilov (1891–1951).
At first, BelOMO made photographic equipment and lens-making machinery for state use. It now manufactures a wide range of products, including military and consumer optical products. During the 1980s it produced the Agat-18 and Agat-18K half-frame 35mm cameras, still popular among Lomographic photographers.
