M4 collimator sight on a M4 mortar. A collimator sight is a type of optical sight that allows the user looking into it to see an illuminated aiming point aligned with the device the sight is attached to, regardless of eye position (with little parallax). [1] They are also referred to as collimating sights [2] or "occluded eye gunsight" (OEG). [3]

On weapons, these sights are usually formed by rugged metal parts, giving them the name "iron sights", [4] as distinct from optical or computing sights. [5] On many types of weapons they are built-in and may be fixed, adjustable, or marked for elevation , windage , target speed, etc. [ 3 ] They are also classified in forms of notch (open sight ...
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.
A red dot sight is a common classification [1] for a non-magnifying reflector (or reflex) sight that provides an illuminated red dot to the user as a point of aim. 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 firearm ...
Assault rifles and sporterized semi-automatic rifles can have foldable rear and front sight elements that can be readily flipped up or down by the user. Such iron sights are often used as secondary sighting systems in case the main weapon sight (typically an optical sight such as a telescopic sight or red dot sight) malfunctions or becomes ...
A reflector sight or reflex sight is an optical sight that allows the user to look through a partially reflecting glass element and see an illuminated projection of an aiming point or some other image superimposed on the field of view.

In 1975 they introduced their first product, [2] the "Aimpoint Electronic" red dot sight, based on a design by Helsingborg engineer John Arne Ingemund Ekstrand. [3]
