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 ...
A view through a Tasco ProPoint red dot sight. The mid- to late 1970s saw the introduction of what are usually referred to as red dot sights, a type that gives the user a simple bright red dot as an aiming point. [27] The typical configuration for this sight is a compact curved mirror reflector design with a red light-emitting diode (LED) at ...
A Royal Canadian Sea Cadet looks through a machine gun sight.. A sight or sighting device is any device used to assist in precise visual alignment (i.e. aiming) of weapons, surveying instruments, aircraft equipment, [1] [2] optical illumination equipment or larger optical instruments with the intended target.
Etched "FinnDot" reticle (a regular mil-dot reticle with the addition of 400 m – 1200 m holdover (stadiametric) rangefinding brackets for 1 meter high or 0.5 meter wide targets at 400, 600, 800, 1000 and 1200 m). Reticle illumination is provided by a tritium ampoule embedded in the elevation turret.
Perhaps the most popular and well-known ranging reticle is the mil-dot reticle, which consists of a duplex crosshair with small dots marking each milliradian (or "mil") intervals from the center. [23] An alternative variant uses perpendicular hash lines instead of dots, and is known as the mil-hash reticle.

The optical window in a holographic weapon sight looks like a piece of clear glass with an illuminated reticle in the middle. The aiming reticle can be an infinitely small dot whose perceived size is given by the acuity of the eye. For someone with 20/20 vision, it is about 1 minute of arc (0.3 mrad). [citation needed]
The PSO-1 pattern range-finding reticle. The bottom-left corner can be used to determine the distance from a 1.7 m tall target A 1.7 m tall person correctly ranged at 400 metres (437 yd) The PSO-1 features a reticle with "floating" elements designed for use in range estimation and bullet drop and drift compensation (see external ballistics).
