Aimpoint AB
Aimpoint AB is a Swedish optics company based in Malmö, Sweden that manufactures red dot sights. Aimpoint is a contractor for the United States military and supplies the Aimpoint CompM2. Aimpoint products are used by various armed forces, and are marketed to civilians for hunting and sport. The Aimpoint Comp sights, such as the CompM2, are Aimpoint's most popular product line. Company Aimpoint is a manufacturing company founded in 1974. Their primary products are reflector (or reflex) sights, specifically the red dot sight sub-type.

Aktiebolag
''Aktiebolag'' (, " stock company") is the Swedish term for "limited company" or "corporation". When used in company names, it is abbreviated AB (in Sweden), Ab (in Finland), or, rarely, A/B (dated), roughly equivalent to the abbreviations ''Ltd.'' and '' PLC''. The state authority responsible for registration of aktiebolag in Sweden is called the Swedish Companies Registration Office. Sweden All ''aktiebolag'' are divided into two categories: private limited companies and public limited companies. The name of a private limited company may not contain the word ''publikt'' ("public") and the name of a public limited company may not contain the word ''privat'' or ''pvt.'' ("private"). Public A public limited company (''publikt aktiebolag'') is legally denoted as "AB (publ.)" in Sweden or "Abp" in Finland. A Swedish public limited company must have a minimum share capital of 500,000 Swedish kronor and its shares can be offered to the general public on the stock market. The ...

Picatinny Rail
The Picatinny rail ( or ), or Pic rail for short, also known as a MIL-STD-1913 rail, 1913 rail or STANAG 2324 rail (cancelled), is a military standard rail interface system that provides a mounting platform for firearm accessories. It was originally used for mounting of scopes atop the receivers of larger caliber rifles. Once established, its use expanded to also attaching other accessories, such as: iron sights, tactical lights, laser aiming modules, night vision devices, reflex sights, holographic sights, foregrips, bipods, slings and bayonets. An updated version of the rail is adopted as a NATO standard as the STANAG 4694 NATO Accessory Rail. Significance Because of their many uses, Picatinny rails and accessories have replaced iron sights in the design of many firearms and available as aftermarket add-on parts for most actions that do not have them integrated, and they are also on the undersides of semi-automatic pistol frames and grips. When adding a Picat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dovetail Rail
A dovetail rail or dovetail mount can refer to several types of sliding rail system found on firearms primarily for mounting telescopic sights. Colloquially, the term ''dovetail rail'' usually refer to any straight mounting bracket with an inverted trapezoid ( dovetail) cross-section (though the hexagonal-profiled Weaver rail and Picatinny rail are also derivative dovetail designs) running parallel to the bore for mounting a scope or diopter sight to a rifle. These are sometimes also called "tip-off" mounts, and allow the user to easily take on or off the sight. ''Dovetail mount'' can also refer to a dovetail track running perpendicular to the bore (see "Other uses" below). Dovetail rails for rifles Dovetails come in several different types and sizes depending on manufacturer, but the most common are the 11 mm and inch (9.5 mm). Some other less known, but currently commercially available dovetail mounts, are 12, 13, 13.5, 14, 14.5, 16, 16.5, 17 and 19 mm, a ...

Zeiss inner rail,ZEISS Hunting Catalogue 2018 "ZEISS revolutionised riflescope mounting? The introduction of the ZEISS inner rail in 1990 meant that gunsmiths no longer needed to perform the laborious tasks of gluing and drilling the mounting components to attach them to the riflescope. Since the patent expired in 2008, the ZEISS inner rail is now offered by almost all prominent European manufacturers." generally simply referred to as Zeiss rail, is a ringless scope sight mounting system introduced by |
Ring 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] |

Optical Axis
An optical axis is a line along which there is some degree of rotational symmetry in an optical system such as a camera lens, microscope or telescopic sight. The optical axis is an imaginary line that defines the path along which light propagates through the system, up to first approximation. For a system composed of simple lenses and mirrors, the axis passes through the center of curvature of each surface, and coincides with the axis of rotational symmetry. The optical axis is often coincident with the system's mechanical axis, but not always, as in the case of off-axis optical systems. For an optical fiber, the optical axis is along the center of the fiber core, and is also known as the ''fiber axis''. See also * Ray (optics) * Cardinal point (optics) * Antenna boresight In telecommunications and radar engineering, antenna boresight is the axis of maximum gain (maximum radiated power) of a directional antenna. For most antennas the boresight is the axis of symmetry of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spherical Aberration
In optics, spherical aberration (SA) is a type of optical aberration, aberration found in optical systems that have elements with spherical surfaces. Lens (optics), Lenses and curved mirrors are prime examples, because this shape is easier to manufacture. Light rays that strike a spherical surface off-centre are refraction, refracted or reflection (physics), reflected more or less than those that strike close to the centre. This deviation reduces the quality of images produced by optical systems. Overview A spherical lens has an Optical aberration#Aberration of elements, i.e. smallest objects at right angles to the axis, aplanatic point (i.e., no spherical aberration) only at a radius that equals the radius of the sphere divided by the index of refraction of the lens material. A typical value of refractive index for crown glass is 1.5 (see List of refractive indices, list), which indicates that only about 43% of the area (67% of diameter) of a spherical lens is useful. It is o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meniscus Corrector
A meniscus corrector is a negative meniscus lens that is used to correct spherical aberration in image-forming optical systems such as catadioptric telescopes. It works by having the equal but opposite spherical aberration of the objective it is designed to correct (usually a spherical mirror). Types Meniscus correctors are used as full aperture correctors, most commonly in a Maksutov telescope sub type called the Gregory or “spot” Maksutov–Cassegrain telescope. They are also used in the Bouwers meniscus telescope. There are Maksutov variations that use the same principle but place the meniscus lens as a sub-aperture corrector near the focus of the objective. There are other sub-aperture meniscus corrector catadioptric telescopes such as the Argunov–Cassegrain telescope and the Klevtsov–Cassegrain telescope. Invention The idea of using the spherical aberration of a meniscus lens to correct the opposite aberration in a spherical objective dates back as far as W. F. Hamil ...
