  • The Quantum LD19S is engineered with germanium glass, allowing for maximum thermal sensory sensitivity. Users have the ability to switch between “white hot” and “black hot,” making targets distinctly visible more than 500 yards away. At 9 frames per second, the LD19S offers a smooth, consistent image, capturing even the fastest-moving objects. 


    The LD19S features 3 new operating modes and calibration modes, allowing users to customize the monocular to their surrounding environment. Equipped with staggered control buttons, the monocular is easily accessible to both right- and left-handed users, and is effortless to locate in pitch black darkness. It features a 10-second start up function to begin viewing quickly. 


    Including two tripod sockets, the monocular can be mounted on a tripod mount with a 1/4" tripod socket. The LD19S also features a standard Weaver rail and tripod mounts, allowing users to attach external power supplies or recording devices. 


    The device features advanced OLED display (640x480) and a high resolution microbolometer sensor (384x288). The longer-distance viewing is made possible by the 2x digital zoom, which increases the 1.1x magnification to 2.2x for a wider field-of-view, and high definition OLED display—the clearest display resolution available on the market. 

  • BODY

    Equipped with durable, glass-nylon composite and a weight of just over one pound, the LD19S is extremely lightweight and weather resistant, able to withstand the harsh environments of the outdoors.
