The company, started in 1907, is on its fifth generation of family ownership.Leeson, Fred (November 17, 1996). "All in the family". ''The Oregonian''. History Leupold & Stevens was founded by the German immigrant Markus Friedrich (Fred) Leupold and his brother-in-law Adam Voelpel in 1907, under the name Leupold & Voelpel. At the time, the company specialized in the repair of survey equipment. In 1911, Leupold & Voelpel was contracted by John Cyprian (J.C.) Stevens to manufacture a water level recorder he had designed and patented. After the initial success of the product, he was made partner in 1914 and the company was renamed Leupold, Voelpel, and Co.Stevens, John Cyprian.

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 practical or pe ...

Scope Mount
Scope mounts are used to attach telescopic sights or other types of sights to firearms. The scope sight itself is usually made for only one of two main types of mounts, which can be classified as ''scopes for ring mounts'' (for example a 30 mm tube) or ''scopes for rail mounts'' (like for example the Zeiss rail). Words such as ''mounts'' and ''bases'' are used somewhat loosely, and can refer to several different parts which are either used together or in place of each other as ways to mount optical sights to firearms. When it comes to the interface of the firearm itself, the Picatinny rail is one of the most widespread standard for new firearms as of 2020. While most scopes are made for being mounted either with a ''ring mount'' or a ''rail mount'', some sights have an integral mounting mechanism allowing them to be attached directly to the firearm, like for example an integrated Picatinny mount. In addition, there are many proprietary and brand-specific types of mounts that e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beaverton, Oregon
Beaverton is a city in Washington County, in the U.S. state of Oregon with a small portion bordering Portland in the Tualatin Valley. The city is among the main cities that make up the Portland metropolitan area. Its population was 97,494 at the 2020 census, making it the second-largest city in the county and the seventh-largest city in Oregon. Beaverton is an economic center for Washington County along with neighboring Hillsboro. It is home to the world headquarters of Nike, Inc., although it sits outside of city limits on unincorporated county land. The hunter–gatherer Atfalati tribe of the Kalapuya people inhabited the Tualatin Valley prior to the arrival of European–American settlers in the 19th century. They occupied a village near the Beaverton and Fanno creeks called Chakeipi, which meant "place of the beaver", and early white settlers referred to this village as Beaverdam. Lawrence Hall took up the first land claim in 1847 and established a grist mill. The entry o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 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 optics; that is, they used a convex objective and a concave eyepiece lens. The Galilean design has the advantage of presenting an erect image but has a narrow field of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 configur ...

List Of Companies Based In Oregon
This is a list of companies based in Oregon. Oregon is the ninth largest by area and the 27th most populous of the 50 United States. The gross domestic product (GDP) of Oregon in 2010 was $168.6 billion; it is the United States's 26th wealthiest state by GDP. The state's per capita personal income in 2010 was $44,447. Oregon has one of the largest salmon-fishing industries in the world, although ocean fisheries have reduced the river fisheries in recent years. The state is home to many breweries, and Portland has the largest number of breweries of any city in the world. High technology industries and services have been major employers since the 1970s. Tektronix was the largest private employer in Oregon until the late 1980s. Intel's creation and expansion of several facilities in eastern Washington County continued the growth that Tektronix had started. Intel is now the state's largest for-profit private employer, with more than 17,000 employees, while Providence Health & Ser ...

Privately Held Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or Over-the-counter (finance), over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their public company, publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

See alsTitle 10, Subtitle B, Chapter 301, Section 3001 The oldest and most senior branch of the U.S. military in order of precedence, the modern U.S. Army has its roots in the Continental Army, which was formed 14 June 1775 to fight the American Revolutionary War (1775–1783)—before the United States was established as a country. After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army.Library of CongressJournals of the Continental Congress, Volume 27/ref> The United States Army considers itself to be a continuation of the Continental Army, and thus considers its institutional inception to be th ...
