ARMASIGHT IR850W Detachable Wide Angle Adjustable Long Range Infrared Illuminator

Part Number: IAIR850IR000002



Armasight extra long-range infrared illuminators provide greater image intensified viewing capabilities for operations in little to no ambient light. Infrared illuminators are used in areas where the level of natural light is not sufficient. An IR illuminator provides near-infrared light which, although invisible to the naked eye, can greatly enhance the performance of night vision devices. The illuminator features adjustments for field of view divergence and output power. Armasight long-range IR illuminators significantly
extend capabilities of night vision weapon sights and observation devices. Our new IR810W and IR850W units provide wide-range beam angle adjustment from 2-20 degrees, which drastically improves the performance of the IR illuminator and extends the user’s nighttime visibility range.
