The '''focus beam''' is a [[Forerunner]] [[laser]] weapon employed by [[monitor]]s and {{Class|Facilitator|ancilla}}.{{Ref/Novel|Id=TRP|TRP|Chapter=38|Quote=Until the submonitor, that small orb of gray alloy and blue light, came barreling up the pass, focus beam raging from her lens, and everything faded away into black...}}{{Ref/Book|Id=enc11|Enc11|Page=237|Quote=Monitors possess a powerful offensive laser much stronger than those of the Sentinels, as well as access to local teleportation grids.}}

==Overview==
The focus beam appears to be a more powerful iteration of the [[Sentinel beam|sterilization beam]] commonly associated to [[Sentinel]]s.{{Ref/Book|Id=Enc22|Enc22|Page=326}} Though, unlike the standard sentinel beam typically mounted on [[Aggressor Sentinel]]s, the focus beam is fired from the monitor's lens on its alloy carapace;{{Ref/Reuse|TRP}} doing so turns the lens' glowing light from its default coloration to red.{{Ref/Level|Id=Floodgate|H3|Floodgate}}{{Ref/Level|Id=Halo|H3|Halo (Halo 3 level)|Halo}}{{Ref/Comic|HE|Issue=10}}{{Ref/Quest|HI|Connections|Conservatory}}{{Ref/Quest|HI|Connections|[[Spire (Halo Infinite level)|Spire]]}} As with all sterilization beams,{{Ref/Reuse|Enc22}} the focus beam could seemingly be tuned for multiple power levels; whereas [[686 Ebullient Prism]]'s focus beam disintegrated [[Reff 'Talamee]]'s body, leaving behind only a heap of gore,{{Ref/Comic|HBL|Issue=5}} when [[343 Guilty Spark]] turned on the [[UNSC]]-[[Sangheili]] team at [[Installation 08]], his initial burst of focus beam only mortally wounded [[Avery Johnson]], even leaving Johnson alive for long enough to assist [[John-117]] in Spark's defeat.{{Ref/Reuse|Halo}}

==Production notes==
In ''Halo: Reach'' [[Forge]], the monitor's default biped weapon is the {{Pattern|M'tara|focus rifle}}, seemingly as a reference to the focus beam used by the monitors in fiction. Fittingly, the focus rifle uses reverse-engineered Forerunner technology,{{Ref/Book|Enc22|Page=293}} particularly copying some aspects of the [[sentinel beam]] and the [[Z-510 focus turret]].{{Ref/Book|H4EVG|Page=103}}{{Ref/Book|Id=OSFM|OSFM|Page=193}}
