Editing Reticle (section)

====Holographic reticles====
[[Holographic weapon sight]]s use a [[hologram|holographic]] image of a reticle at finite set range built into the viewing window and a [[collimated light|collimated]] [[laser diode]] to illuminate it.  An advantage to holographic sights is that they eliminate a type of [[parallax]] problem found in some optical collimator based sights (such as the [[red dot sight]]) where the spherical mirror used induces [[spherical aberration]] that can cause the reticle to skew off the sight's [[optical axis]]. The use of a hologram also eliminates the need for image dimming narrow band reflective coatings and allows for reticles of almost any shape or [[milliradian|mil]] size. A downside to the holographic weapon sight can be the weight and shorter battery life. As with red dot sights, holographic weapon sights have also become common on small arms with versions like the [[EOTech|Eotech]] 512.A65 and similar models fielded by the U.S. Military<ref>{{cite web |url=http://www.defenseindustrydaily.com/Holographic-Sights-for-SOCOM-M4s-06416/ |title=Holographic Sights for SOCOM M4s |access-date=30 August 2012}}</ref>  and various law enforcement agencies.
