Rubinar
Rubinar (russian: Рубинар) 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. Rubinars can be used with proprietary mount cameras by using M42 adaptors. Focusing motors are absent though (manual only), and so are the variable apertures. Variants * MC Rubinar - 1:8.0 500 mm * MC Rubinar - 1:4.5 300 mm * MC Rubinar - 1:5.6 500 mm * MC Rubinar - 1:10 1000 mm * Rubinars may be transformed into spotting scope A spotting scope is a compact high-power telescope optimized for detailed observation of distant objects.

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

Photographic Lens
A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically. There is no major difference in principle between a lens used for a still camera, a video camera, a telescope, a microscope, or other apparatus, but the details of design and construction are different. A lens might be permanently fixed to a camera, or it might be interchangeable with lenses of different focal lengths, apertures, and other properties. While in principle a simple convex lens will suffice, in practice a compound lens made up of a number of optical lens elements is required to correct (as much as possible) the many optical aberrations that arise. Some aberrations will be present in any lens system. It is the job of the lens designer to balance these and produce a desi ...

Joint Stock Company
A joint-stock company is a business entity in which shares of the company's stock can be bought and sold by shareholders. Each shareholder owns company stock in proportion, evidenced by their shares (certificates of ownership). Shareholders are able to transfer their shares to others without any effects to the continued existence of the company. In modern-day corporate law, the existence of a joint-stock company is often synonymous with incorporation (possession of legal personality separate from shareholders) and limited liability (shareholders are liable for the company's debts only to the value of the money they have invested in the company). Therefore, joint-stock companies are commonly known as corporations or limited companies. Some jurisdictions still provide the possibility of registering joint-stock companies without limited liability. In the United Kingdom and in other countries that have adopted its model of company law, they are known as unlimited companies. In t ...

Focal Length
The focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system's optical power. A positive focal length indicates that a system converges light, while a negative focal length indicates that the system diverges light. A system with a shorter focal length bends the rays more sharply, bringing them to a focus in a shorter distance or diverging them more quickly. For the special case of a thin lens in air, a positive focal length is the distance over which initially collimated (parallel) rays are brought to a focus, or alternatively a negative focal length indicates how far in front of the lens a point source must be located to form a collimated beam. For more general optical systems, the focal length has no intuitive meaning; it is simply the inverse of the system's optical power. In most photography and all telescopy, where the subject is essentially infinitely far away, longer focal length (lower opti ...

M42 Lens Mount
The M42 lens mount is a screw thread mounting standard for attaching lenses to 35 mm cameras, primarily single-lens reflex models. It is more accurately known as the M42 × 1 mm standard, which means that it is a metric screw thread of 42 mm diameter and 1 mm thread pitch. (The M42 lens mount should not be confused with the T-mount, which shares the 42mm throat diameter, but differs by having a 0.75mm thread pitch.) It was first used by the East German brands VEB Zeiss Ikon in the Contax S of 1949, and KW in the Praktica of the same year. VEB Zeiss Ikon and KW were merged into the Pentacon brand in 1959, along with several other East German camera makers. M42 thread mount cameras first became well known under the Praktica brand, and thus the M42 mount is known as the Praktica thread mount.The M42 mount is sometimes referred to as a "P" thread. See, e.g., Since there were no proprietary elements to the M42 mount, many other manufacturers used it; this ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spotting Scope
A spotting scope is a compact high-power telescope optimized for detailed observation of distant objects. They are used as portable optical enhancement devices for various outdoor activities such as birdwatching, skygazing and other naturalist activities, for hunting and target shooting to verify a marksman's shot placements, for tactical ranging and surveillance, and for any other application that requires higher magnification than ordinary binoculars (typically 20× to 60×). The light-gathering power and resolution of a spotting scope is determined by the diameter of the objective lens, typically between . The larger the objective, the more massive and expensive the telescope. The optical assembly has a small refracting objective lens, an internal image-erecting system, and an eyepiece that is usually removable. The image-erecting system may use relay lenses, prisms such as Porro or roof prisms, or a catadioptric system of the Schmidt or Maksutov design. Spotting ...
