Meopta
Meopta - optika, s.r.o. is a Czech Republic based company that manufactures various products mainly in the field of optics. The company was once well-known for its still and movie cameras, although it no longer manufactures such products. History Optikotechna company was founded in 1933 in Přerov, Czechoslovakia. Originally established with the intention of producing a limited range of lenses and condensers, the company rapidly expanded the range of products to include enlargers, composite lenses, binoculars, riflescopes, cameras and slide projectors. After 1935, Meopta optika became a subsidiary of Zbrojovka Brno and a major supplier of military optics for the Czechoslovak Army. Company retained its focus on military production when it was seized by Germans during the occupation of Czechoslovakia as well as after WW2, when it was nationalized and renamed to Meopta – an acronym for MEchanická OPTická výrobA ("mechanical optical manufacturing"). In 1945 the company merged w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Přerov
Přerov (; german: Prerau) is a city in the Olomouc Region of the Czech Republic. It has about 41,000 inhabitants. It lies on the Bečva River. In the past it was a major crossroad in the heart of Moravia in the Czech Republic. The historic centre of the town is well preserved and is protected by law as an urban monument zone.

Flexaret
Flexaret is a brand of cameras manufactured from 1939 to 1970 in Czechoslovakia by the company Meopta. All models of Flexaret are twin-lens reflex cameras with aluminum body, taking square "6×6" format photographs on a 120 roll film. Some models were also capable of using 35 mm film with the help of a special adapter. History In 1939, the company Optikotechna bought a factory producing photographic equipment in Přerov. Optikotechna initially developed and improved older models (known as Autoflex and Flexette). The development of a new camera called Flexaret started in the post- World War II years in the Meopta company, founded in 1946. The camera was intended rather for amateur photography; the handling was easy and technical parameters were simple. The Flexaret rapidly became popular in Czechoslovak households and its popularity lasted until the 1960s. However, the strategy of the Council for Mutual Economic Assistance among communist states demanded subordination of nationa ...

Subminiature Photography
Subminiature photography is photographic technologies and techniques working with film material smaller in size than 35mm film, such as 16mm, 9.5mm, 17mm, or 17.5mm films. It is distinct from photomicrography, photographing microscopic subjects with a camera which is not particularly small. Definition Subminiature — "very much reduced in size", Oxford English Dictionary. A subminiature camera is a class of camera that is very much smaller than a "miniature camera". The term "miniature camera" was originally used to describe cameras using the 35 mm cine film as negative material for still photography; so cameras that used film smaller than 35mm were referred to as "sub-miniature"."SUBMINIATURE CAMERA A common reference to a group of cameras using formats smaller than 35 mm.

Telescopic Sight
A telescopic sight, commonly called a scope informally, is an optical sighting device based on a refracting telescope. It is equipped with some form of a referencing pattern – known as a '' reticle'' – mounted in a focally appropriate position in its optical system to provide an accurate point of aim. Telescopic sights are used with all types of systems that require magnification in addition to reliable visual aiming, as opposed to non-magnifying iron sights, reflector (reflex) sights, holographic sights or laser sights, and are most commonly found on long-barrel firearms, particularly rifles, usually via a scope mount. The optical components may be combined with optoelectronics to add night vision or smart device features. History The first experiments directed to give shooters optical aiming aids go back to the early 17th century. For centuries, different optical aiming aids and primitive predecessors of telescopic sights were created that had practica ...

Binoculars
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 (binocular vision) 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. Unlike a (monocular) telescope, binoculars give users a stereopsis, three-dimensional image: each eyepiece presents a slightly different image to each of the viewer's eyes and the parallax allows the visual cortex to generate an depth perception, impression of depth. Optical designs Galilean Almost from the invention of the telescope in the 17th century the advantages of mounting two of them side by side for binocular vision seems to have been explored. Most early binoculars used Galilean telescope, Galilean optics; that is, they used a convex lens, convex objective (optics), objective and a concave lens, concave eyepiece, eyep ...

Cameras
A camera is an optical instrument that can capture an image. Most cameras can capture 2D images, with some more advanced models being able to capture 3D images. At a basic level, most cameras consist of sealed boxes (the camera body), with a small hole (the aperture) that allows light to pass through in order to capture an image on a light-sensitive surface (usually a digital sensor or photographic film). Cameras have various mechanisms to control how the light falls onto the light-sensitive surface. Lenses focus the light entering the camera, and the aperture can be narrowed or widened. A shutter mechanism determines the amount of time the photosensitive surface is exposed to the light. The still image camera is the main instrument in the art of photography. Captured images may be reproduced later as part of the process of photography, digital imaging, or photographic printing. Similar artistic fields in the moving-image camera domain are film, videography, and cinemato ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lens Manufacturers
A lens is a transmissive optical device which focuses or disperses a light beam by means of refraction. A simple lens consists of a single piece of transparent material, while a compound lens consists of several simple lenses (''elements''), usually arranged along a common axis. Lenses are made from materials such as glass or plastic, and are ground and polished or molded to a desired shape. A lens can focus light to form an image, unlike a prism, which refracts light without focusing. Devices that similarly focus or disperse waves and radiation other than visible light are also called lenses, such as microwave lenses, electron lenses, acoustic lenses, or explosive lenses. Lenses are used in various imaging devices like telescopes, binoculars and cameras. They are also used as visual aids in glasses to correct defects of vision such as myopia and hypermetropia. History The word ''lens'' comes from '' lēns'', the Latin name of the lentil (a seed of a lentil plant), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Companies Of Czechoslovakia
A company, abbreviated as co., is a legal entity representing an association of people, whether natural, legal or a mixture of both, with a specific objective. Company members share a common purpose and unite to achieve specific, declared goals. Companies take various forms, such as: * voluntary associations, which may include nonprofit organizations * business entities, whose aim is generating profit * financial entities and banks * programs or educational institutions A company can be created as a legal person so that the company itself has limited liability as members perform or fail to discharge their duty according to the publicly declared incorporation, or published policy. When a company closes, it may need to be liquidated to avoid further legal obligations. Companies may associate and collectively register themselves as new companies; the resulting entities are often known as corporate groups.

Photography Companies Of The Czech Republic
Photography is the art, application, and practice of creating durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purpose ...

Monocular
A monocular is a compact refracting telescope used to magnify images of distant objects, typically using an optical prism to ensure an erect image, instead of using relay lenses like most telescopic sights. The volume and weight of a monocular are typically less than half of a pair of binoculars with similar optical properties, making it more portable and also less expensive. This is because binoculars are essentially a pair of monoculars packed together — one for each eye. As a result, monoculars only produce two-dimensional images, while binoculars can use two parallaxed images (each for one eye) to produce binocular vision, which allows stereopsis and depth perception. Monoculars are ideally suited to those application where three-dimensional perception is not needed, or where compactness and low weight are important (e.g. hiking). Monoculars are also sometimes preferred where difficulties occur using both eyes through binoculars due to significant eyesight variatio ...

Red Dot Sight
A red dot sight is a common classification for a type of non- magnifying reflector (or reflex) sight for firearms, and other devices that require aiming, that gives the user a point of aim in the form of an illuminated red dot. A standard design uses a red light-emitting diode (LED) at the focus of collimating optics which generates a dot-style illuminated reticle that stays in alignment with the weapon the sight is attached to, regardless of eye position (nearly parallax free). They are considered to be fast-acquisition and easy-to-use gun sights for civilian target shooting, hunting, or in police and military applications. Aside from firearm applications, they are also used on cameras and telescopes. On cameras they are used to photograph flying aircraft, birds in flight, and other distant, quickly moving subjects. Telescopes have a narrow field of view and therefore are often equipped with a secondary "finder scope" such as a red dot sight. Description The typical configu ...
