Rubinar 500mm 5 6 V04
Rubinar () is a Soviet Union, Soviet photographic lens, lens design series developed and produced by Joint stock company, 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 lens mount, 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 scopes using an M42 ''Turist-FL'' ocular attachment and image redresser. Their optical arrangement gives flexibility in placing the focal plane and changing the focal ratio by mere refocus. * Astro-Rubinar is a Rubinar 1000 mm kit including oculars and a 90° prism for convenient use as a visual telescope. * MTO lenses by Soviet manufacturer Krasnogorsky Zavod, KMZInformation about the KMZ ZeniMTO-500anMTO-1000 ...

Soviet Union
The Union of Soviet Socialist Republics. (USSR), commonly known as the Soviet Union, was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 until Dissolution of the Soviet Union, it dissolved in 1991. During its existence, it was the list of countries and dependencies by area, largest country by area, extending across Time in Russia, eleven time zones and sharing Geography of the Soviet Union#Borders and neighbors, borders with twelve countries, and the List of countries and dependencies by population, third-most populous country. An overall successor to the Russian Empire, it was nominally organized as a federal union of Republics of the Soviet Union, national republics, the largest and most populous of which was the Russian SFSR. In practice, Government of the Soviet Union, its government and Economy of the Soviet Union, economy were Soviet-type economic planning, highly centralized. As a one-party state go ...

Photographic Lens
A camera lens, photographic lens or photographic objective is an optical lens (optics), lens or assembly of lenses (compound lens) used in conjunction with a camera body and mechanism to Imaging, make images of objects either on photographic film or on other media capable of storing an image Photosensitivity, chemically or Image sensor, 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 lens camera, interchangeable with lenses of different focal lengths, apertures, and other properties. While in principle a simple lens, 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 prese ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Joint Stock Company
A joint-stock company (JSC) is a business entity in which shares of the company's capital stock, stock can be bought and sold by shareholders. Each shareholder owns company stock in proportion, evidenced by their share (finance), shares (certificates of ownership). Shareholders are able to transfer their shares to others without any effects to the Perpetual succession, continued existence of the company. In modern-day corporate law, the existence of a joint-stock company is often synonymous with incorporation (business), 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 company, limited companies. Some jurisdiction (area), jurisdictions still provide the possibility of registering joint-stock companies without limited liability. In the Unite ...

Lytkarino Plant Of Optical Glass
Lytkarino Optical Glass Plant () is a company based in Lytkarino, Russia and established in 1934. It is part of the Shvabe Holding of the state-owned Rostec corporation. The Lytkarino Optical Glass Plant is a major producer of optical glass and precision optical instruments for the military as well as for the civilian market, producing night vision devices and glass laser optics. History On October 1, 1933 Order №887/204 of the All-Union Trust of the Optical and Mechanical Industry of the People's Commissariat of Heavy Industry of the USSR (NKTP) was signed on the construction of a mirror reflector plant near the village of Lytkarino in the Ukhtomsky district of the Moscow Region (ZZO — the name of the plant before its renaming) for searchlight installations with mirrors up to 150 cm in diameter. The plant began to be built in 1934-1935. In 1939 the unfinished plant produced its first products – five searchlight mirrors with a diameter of 1.5 meters. At that time, only fa ...

Focal Length
The focal length of an Optics, optical system is a measure of how strongly the system converges or diverges light; it is the Multiplicative inverse, inverse of the system's optical power. A positive focal length indicates that a system Convergence (optics), converges light, while a negative focal length indicates that the system Divergence (optics), diverges light. A system with a shorter focal length bends the Ray (optics), 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 beam, collimated (parallel) rays are brought to a Focus (optics), 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 mos ...

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 42 mm throat diameter, but differs by having a 0.75 mm 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 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Spotting Scope
A spotting scope is a compact lightweight portable telescope optimized for detailed observation of distant objects. They are used as tripod mounted 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 ...
