56-427: A Porro prism . Reticle A reticle , or reticule also known as a graticule , is a pattern of fine lines or markings built into the eyepiece of an optical device such as a telescopic sight , spotting scope , theodolite , optical microscope or the screen of an oscilloscope , to provide measurement references during visual inspections . Today, engraved lines or embedded fibers may be replaced by

84-543: A digital image superimposed on a screen or eyepiece. Both terms may be used to describe any set of patterns used for aiding visual measurements and calibrations , but in modern use reticle is most commonly used for weapon sights , while graticule is more widely used for non-weapon measuring instruments such as oscilloscope display , astronomic telescopes , microscopes and slides , surveying instruments and other similar devices. There are many variations of reticle pattern; this article concerns itself mainly with

112-401: A holographic image of a reticle at finite set range built into the viewing window and a collimated laser diode to illuminate it. An advantage to holographic sights is that they eliminate a type of parallax problem found in some optical collimator based sights (such as the red dot sight ) where the spherical mirror used induces spherical aberration that can cause the reticle to skew off

140-428: A complex background, but lack the precision of thin bars. The most popular types of cross-hair in modern scopes are variants on the duplex cross-hair, with bars that are thick on the perimeter and thin out in the middle. The thick bars allow the eye to quickly locate the center of the reticle, and the thin lines in the center allow for precision aiming. The thin bars in a duplex reticle may also be designed to be used as

168-574: A measure. Called a 30/30 reticle, the thin bars on such a reticle span 30 minutes of arc (0.5º), which is approximately equal to 30 inches at 100 yards or 90 centimeters at 100 meters. This enables an experienced shooter to deduce, on the basis of the known size of an object in view, (as opposed to guess or estimate) the range within an acceptable error limit. Originally crosshairs were constructed out of hair or spiderweb, these materials being sufficiently thin and strong. Many modern scopes use wire crosshairs, which can be flattened to various degrees to change

196-486: A precision pointer . The reticle is said to have been invented by Robert Hooke , and dates to the 17th century. Another candidate as inventor is the amateur astronomer William Gascoigne , who predated Hooke. The term reticle comes from the Latin reticulum , meaning small net. Telescopic sights for firearms, generally just called scopes , are probably the device most often associated with crosshairs. Motion pictures and

224-413: A reticle that indicates the position of Polaris relative to the north celestial pole. Telescopes that are used for very precise measurements would have a filar micrometer as a reticle; this could be adjusted by the operator to measure angular distances between stars. For aiming telescopes, reflex sights are popular, often in conjunction with a small telescope with a crosshair reticle. They make aiming

252-472: Is different from Wikidata All article disambiguation pages All disambiguation pages NOBLEX E-Optics GmbH The company grew out of binocular production by the forerunner of Carl Zeiss AG before World War Two. In 1952 a part of the company VEB Carl Zeiss Jena was established in Eisfeld in what was then East Germany . Starting from tasks as supplier of parts and pre-assembling products for

280-409: Is near zero if the glass is multicoated (coating being the norm for all modern high quality optical products). Reticles may be illuminated, either by a plastic or fiber optic light pipe collecting ambient light or, in low light conditions, by a battery powered LED . Some sights also use the radioactive decay of tritium for illumination that can work for 11 years without using a battery, used in

308-476: Is that they are fairly tough and durable, and provide no obstruction to light passing through the scope. The first suggestion for etched glass reticles was made by Philippe de La Hire in 1700. His method was based on engraving the lines on a glass plate with a diamond point. Many modern crosshairs are actually etched onto a thin plate of glass , which allows a far greater latitude in shapes. Etched glass reticles can have floating elements, which do not cross

336-747: The British SUSAT sight for the SA80 (L85) assault rifle and in the American ACOG (Advanced Combat Optical Gunsight) . Red is the most common color used, as it is the least destructive to the shooter's night vision , but some products use green or yellow illumination, either as a single colour or changeable via user selection. Another term for reticle is graticule , which is frequently encountered in British and British military technical manuals. It came into common use during World War I . The reticle may be located at

364-550: The Eisfeld plant of the Jenoptik Carl Zeiss Jena GmbH, which employed 550 staff, was taken over by Bernhard Docter, who lent his name to the company and products. The company now traded under the name Docter-Optic-Eisfeld GmbH and continued with the production of binoculars, riflescopes, spotting scopes, magnifying glasses and opto-electronic measurement equipment. The company Docter-Optic in Wetzlar declared bankruptcy for

392-643: The U.S. Military and various law enforcement agencies. In older instruments, reticle crosshairs and stadia marks were made using threads taken from the cocoon of the brown recluse spider . This very fine, strong spider silk makes for an excellent crosshair. In surveying, reticles are designed for specific uses. Levels and theodolites would have slightly different reticles. However, both may have features such as stadia marks to allow distance measurements. For astronomical uses, reticles could be simple crosshair designs or more elaborate designs for special purposes. Telescopes used for polar alignment could have

420-675: The Zeiss factories in Jena the company continuously developed over the following years to become a producer of precision-engineered optical consumer goods and industrial products. Besides that VEB Carl Zeiss Jena produced military optics for the armed forces of the German Democratic Republic (GDR) like the NVA DF 7x40 and NVA EDF 7x40 roof prism binoculars . A year after the German reunification ,

448-470: The following series: The number in the naming stands for the zoom factor. All of the Noblex rifle scopes come with illuminated reticle as standard. Noblex is also producing the following binoculars in 2019. They are all produced in Jena and ED models feature magnesium housing and Open Bridge design. Noblex also produces a single monocular called Noblex Mono 8x21 which has an unusual design incorporating

476-544: The following variants: Noblex QuickSights is significantly different that all other Noblex Red Dot Sights, since it is designed to fit on shotguns and to mount directly on shotgun ribs. It comes with 5.0 MOA dot as standard. The rest Noblex Sights share the same footprint that became an industry standard and is used also by brands like Meopta , Vortex Optics , Leica Camera and others. They come with either 3.5 MOA red dot (for rifle use) or with 7.0 MOA red dot (for handgun use). Riflescopes produced by Noblex are divided in

504-483: The front or rear focal plane (First Focal Plane (FFP) or Second Focal Plane (SFP)) of the telescopic sight. On fixed power telescopic sights there is no significant difference, but on variable power telescopic sights the front plane reticle remains at a constant size compared to the target, while rear plane reticles remain a constant size to the user as the target image grows and shrinks. Front focal plane reticles are slightly more durable, but most American users prefer that

532-447: The media often use a view through crosshairs as a dramatic device, which has given crosshairs wide cultural exposure. While the traditional thin crossing lines are the original and still the most familiar cross-hair shape, they are really best suited for precision aiming at high contrast targets, as the thin lines are easily lost in complex backgrounds, such as those encountered while hunting. Thicker bars are much easier to discern against

560-552: The most rudimentary reticle: the crosshair . Crosshairs are typically represented as a pair of perpendicularly intersecting lines in the shape of a cross, "+", though many variations of additional features exist including dots, posts , concentric circles / horseshoes , chevrons , graduated markings , or a combination of above. Most commonly associated with telescopic sights for aiming firearms , crosshairs are also common in optical instruments used for astronomy and surveying , and are also popular in graphical user interfaces as

588-476: The operator needed a wide field of view to track and range a moving target visually (i.e. weapons from the pre laser / radar / computer era). More recently sights using low power consumption durable light emitting diodes as the reticle (called red dot sight s) have become common on small arms with versions like the Aimpoint CompM2 being widely fielded by the U.S. Military. Holographic weapon sights use

616-491: The process of re-branding started and most of the products received Noblex brand name. Most of the older model lines were discontinued in 2018 and new products lines were renamed in accordance with the Noblex brand nomenclature. Since the beginning of 2019 Noblex Optics is producing Binoculars , Telescopic sights , Red dot sights and Monoculars . Majority of their production is concentrated on their Red Dot Sights, which are well known globally. Noblex Sights are produced in

644-412: The reticle remains constant as the image changes size, so nearly all modern American variable power telescopic sights are rear focal plane designs. American and European high end optics manufacturers often leave the customer the choice between a FFP or SFP mounted reticle. Collimated reticles are produced by non-magnifying optical devices such as reflector sights (often called reflex sights ) that give

672-408: The reticle; circles and dots are common, and some types of glass reticles have complex sections designed for use in range estimation and bullet drop and drift compensation (see external ballistics ). A potential disadvantage of glass reticles is that the surface of the glass reflects some light (about 4% per surface on uncoated glass ) lessening transmission through the scope, although this light loss

700-476: The sight's optical axis . The use of a hologram also eliminates the need for image dimming narrow band reflective coatings and allows for reticles of almost any shape or mil size. A downside to the holographic weapon sight can be the weight and shorter battery life. As with red dot sights, holographic weapon sights have also become common on small arms with versions like the Eotech 512.A65 and similar models fielded by

728-560: The viewer an image of the reticle superimposed over the field of view, and blind collimator sights that are used with both eyes. Collimated reticles are created using refractive or reflective optical collimators to generate a collimated image of an illuminated or reflective reticle. These types of sights are used on surveying/triangulating equipment, to aid celestial telescope aiming, and as sights on firearms . Historically they were used on larger military weapon systems that could supply an electrical source to illuminate them and where

756-509: The whole business on 15 November 1995. On 1 May 1997 a part of the business with 40 staff was continued by Analytik Jena GmbH, to which traditionally good relations existed. Already the first year after the takeover was completed with very good turnover and results. By 2006 Docter Optics employed 100 staff. On 1 May 2016 Docter Optics was acquired by Noblex GmbH, a subsidiary of the Frankfurt holding company VF Capital GmbH. At IWA Show in 2018

784-473: The width. These wires are usually silver in color, but appear black when backlit by the image passing through the scope's optics. Wire reticles are by nature fairly simple, as they require lines that pass all the way across the reticle, and the shapes are limited to the variations in thickness allowed by flattening the wire; duplex crosshairs, and crosshairs with dots are possible, and multiple horizontal or vertical lines may be used. The advantage of wire crosshairs
