Multi-Function Uncooled Thermal Binocular




IR521 Uncooled Multi-Function Thermal Binocular
(Below called Imager), as imager, is using for detect the state of
the enemy and landform in bad weather or night to assist
improving the effect of target detection and shooting
performance. The product combines infrared Imager, visible
light and laser ranging finder together. It can be used for long
distance detection for day and night by individual soldier. It can
offer the soldier’s geographic coordinates, distance of the target
and the geographic coordinates of the target. It can improve the
detection power and master battle orientation to gain the
initiative in battle and give direct assistant to the soldier to help
them control the battlefield.
