Binoculars or field glasses are two refracting telescopes mounted side-by-side and aligned to point in the same direction, allowing the viewer to use both eyes when viewing distant objects. Most binoculars are sized to be held using both hands, although sizes vary widely from opera glasses to large pedestal-mounted military models.
LOMO is a manufacturer of medical and motion-picture lenses and equipment based in St. Petersburg, Russia. The company was awarded three Order of Lenin decorations by the Soviet Union.
Dmitry Dmitrievich Maksutov was a Soviet optical engineer and amateur astronomer. He is best known as the inventor of the Maksutov telescope.
A catadioptric optical system is one where refraction and reflection are combined in an optical system, usually via lenses (dioptrics) and curved mirrors (catoptrics). Catadioptric combinations are used in focusing systems such as searchlights, headlamps, early lighthouse focusing systems, optical telescopes, microscopes, and telephoto lenses. Other optical systems that use lenses and mirrors are also referred to as "catadioptric", such as surveillance catadioptric sensors.
In optics, a Mangin mirror is a negative meniscus lens with the reflective surface on the rear side of the glass forming a curved mirror that reflects light without spherical aberration if certain conditions are met. This reflector was invented in 1874 by a French officer Alphonse Mangin as an improved catadioptric reflector for search lights and is also used in other optical devices.
Rubinar is a Soviet lens design series developed and produced by JSC Lytkarino Plant of Optical Glass (LZOS). It is compact despite its long focal lengths.

Joint-Stock Company Moscow Distillery Crystal, formerly known as Moscow State Wine Warehouse No. 1, is a distillery in Moscow, Russia, known for producing traditional Russian vodka. Founded in 1901 as a state-sanctioned distillery, Kristall is the largest liquor and vodka enterprise in Russia, and is best known internationally as the birthplace of the Stolichnaya vodka brand.
Precision glass moulding is a replicative process that allows the production of high precision optical components from glass without grinding and polishing. The process is also known as ultra-precision glass pressing. It is used to manufacture precision glass lenses for consumer products such as digital cameras, and high-end products like medical systems. The main advantage over mechanical lens production is that complex lens geometries such as aspheres can be produced cost-efficiently.
Ventprom is a Russian machine building plant located in Artyomovsky, Sverdlovsk Oblast, Russia. The factory produces ventilation equipment, such as main mine ventilation fans, for a number of large mining companies, including Lukoil, SUAL Group and others. The full name of the company is Joint Stock Company Artyomovsky Machine Engineering Plant VENTPROM. It is a private company. The name ВЕНТПРОМ means "fan industry".
