type of weapon sight


A sight is an aiming device used to assist in visually aligning ranged weapons, surveying instruments or optical illumination equipments with the intended target. Sights can be a simple set or system of markers that have to be aligned together with the target (such as iron sights on firearms),[1] or optical devices that allow the user to see a sometimes optically enhanced (e.g. magnified) image of the target aligned in the same focus with an aiming point (e.g. telescopic sights, reflector sights and holographic sights). There are also sights that project an aiming point (or a "hot spot") onto the target itself, such as laser sights and infrared illuminators on some night vision devices.

Optical sights use optics that give the user an image of an aligned aiming point or pattern (also called a reticle) superimposed at the same focus as the target.[citation needed]

Telescopic sights
A telescopic sight is an optical telescope equipped with some form of graphic image pattern reticle mounted in an optically appropriate position in the optical system to give an accurate aiming point. Telescopic sights are used on a wide range of devices including guns, surveying equipment, and even as sights on larger telescopes (called a finderscope).

Reflector sights
Another type of optical sight is the reflector (or "reflex") sight, a generally non-magnifying optical device that allows the user to look through a glass element and see a reflection of an illuminated aiming point or some other image superimposed on the field of view.[5] These sights have been around for over 100 years and been used on all types of weapons and devices.

Reflector sights were first used as a weapon sight in German aircraft towards the end of World War I. Over the years they became more sophisticated, adding lead computing gyroscopes and electronics (the World War II Gyro gunsight)[6] radar range finding and other flight information in the 1950s and 60s, eventually becoming the modern head-up display.

There are many types of sighting devices. They can be fixed, mechanical, optical, computational, or a mixture of all of these attributes.

Laser sight
The laser has in most firearms applications been used as a tool to enhance the targeting of other weapon systems. For example, a laser sight is a small, usually visible-light laser placed on a handgun or a rifle and aligned to emit a beam parallel to the barrel. Since a laser beam has low divergence, the laser light appears as a small spot even at long distances; the user places the spot on the desired target and the barrel of the gun is aligned (but not necessarily allowing for bullet drop, windage, distance between the direction of the beam and the axis of the barrel, and the target mobility while the bullet travels).

Most laser sights use a red laser diode. Others use an infrared diode to produce a dot invisible to the naked human eye but detectable with night vision devices. The firearms adaptive target acquisition module LLM01 laser light module combines visible and infrared laser diodes. In the late 1990s, green diode pumped solid state laser (DPSS) laser sights (532 nm) became available. Modern laser sights are small and light enough for attachment to the firearms.

In 2007, LaserMax, a company specializing in manufacturing lasers for military and police firearms, introduced the first mass-production green laser available for small arms.[20] This laser mounts to the underside of a handgun or long arm on the accessory rail. The green laser is supposed to be more visible than the red laser in bright lighting conditions because, for the same wattage, green light appears brighter than red light.
