[[File:Reflector reflex sight diagram 3.png|thumb|right|Diagram of three types of reflector sights that produce collimated reticles. The top uses a collimating lens (CL) and a beam splitter (B) to create a [[virtual image]] at infinity (V) of a reticle (R). The bottom two use half silvered curved mirrors (CM) as the collimating optics with the reticle off-set or between the mirror and the observer.]]

Collimated reticles are produced by non-magnifying optical devices such as [[reflector sight]]s (often called ''reflex sights'') that give the viewer an image of the reticle superimposed over the field of view, and blind [[collimator sight]]s that are used with both eyes. Collimated reticles are created using [[refraction|refractive]] or [[reflection (physics)|reflective]] [[Collimator#Optical collimators|optical collimators]] to generate a [[Collimated light|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 [[gunsights|sight]]s on [[firearm]]s.  Historically they were used on larger military weapon systems that could supply an electrical source to illuminate them and where 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 diode]]s 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.
