Armasight is proud to introduce its exclusive, revolutionary new approach to night vision - COPRE (Ceramic Optical Ruggedized Engine) image intersifier tubes! While CORE does not contain a microchannel plate (and so by definition lands in the Gen 1 category), that is where the parallels end. Instead of glass, CORE tubes use a specially formulated ceramic compound fused with metal alloys similar to those used in production of Gen 2 and Gen 3 image intensifier tubes. Further advances in CORE technology have removed almost all edge distortion, dramatically increased photocathode sensitivity, and nearly doubled resolution up to 55 lp/mm! The Armasight Spark is the ideal night vision unit for the outdoorsman or first responder who demands higher resolution, better image clarity and greater durability than any standard Gen 1 unit can offer.
