Utilizing uncooled microbolometer technology, the SpecterIR is a completely passive infrared weapon sighting system which allows users to identify the heat signatures of individuals or objects; day or night and in rain, fog and smoke. No external light source is required, and the unit may be used in complete darkness or broad daylight. When viewed through the SpecterIR, heat-emitting objects such as humans and recently-operated vehicles stand out dramatically against their surroundings, defeating camouflage and other methods of visual concealment.
Built to the same legendary rugged standards as other ELCAN weapon sighting systems, the SpecterIR is a shock and water-resistant sight that will withstand the forces generated by repeated recoil. The quick-detachable mount allows fast attachment to Mil-Std-1913 "Picatinny” rails and weapon receivers. Once sighted-in to a particular weapon, the sight may be interchanged with other ELCAN optical and electro-optical sights zeroed for the same weapon in a matter of seconds and without noticeable change in point of impact. The electronic reticle allows precise targeting of hostile threats.

The SpecterIR operates on three lithium AA batteries and has auxiliary power ports for operation on AC electrical outlets or vehicle cigarette lighters. A video output port allows the image to be displayed on an external video monitor or recorded by video recorder. When used solely as an observation device, the unit may be operated hand-held or tripod mounted.
