<P> A red dot sight is a common classification for a type of non-magnifying reflector ( or reflex ) sight for firearms , and other devices that require aiming , that gives the user an aimpoint in the form of an illuminated red dot . 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 weapon the sight is attached to regardless of eye position ( nearly parallax free ) . They are considered to be fast acquisition and easy to use gun sights for target shooting , hunting , and in police and military applications . Aside from firearm applications , they are also used on cameras and telescopes . On cameras they are used to photograph flying aircraft , birds in flight , and other distant , quickly moving subjects . Telescopes have a narrow field of view and therefore are often equipped with a secondary `` finder scope '' such as a red dot sight . </P>
