As technology continues to thrive, the systems involved with the development of thermal scopes improved, giving rise to uses such as those for military purposes and recreational activities. For the latter purposes, thermal imaging scopes have been used more since they can be mounted on the weapon itself. For those looking for a thermal weapon sight without breaking the bank, it might be worth looking at the Armasight Zeus 4 160-30.
Futuristic and rugged in concept, the Zeus 4 is a well-built thermal imaging weapon scope that measures 10” long, 2.8” wide, and 3.2”high. It is lightweight at 1.5 pounds, enabling it to be mounted easily on the rifle without adding too much weight on it. Its sturdy dark-colored structure is designed to be used to withstand almost any environmental condition and can be submerged to depths of up to 10m for about 30 minutes. As it is meant to be mounted on a rifle, it is also designed to resist recoil of up to 700g. The thermal scope can be attached to the rifle with the use of a Picatinny MIL STD 1913 weapon mount with Weaver Rails for additional support. Two CR 123A batteries are needed for this device to work properly. Under environmental temperatures of 20 degrees C (68 degrees F), the unit is expected to work continuously for up to 4 hours.
The unit is equipped with a160x120 FLIR Tau 2 FPA microbolometer, which offers an impressive thermal imaging. It also is fitted with an AMOLED SVGA 060 display with an 800×600 pixel format. The display’s brightness can be adjusted easily to 8 levels according to your preference. Digital zooming technology is present in this thermoscope with adjustable zooming levels of 1x, 2x, and 4x. Image palettes can also be changed in 13 different imaging modes which include Ironbow 1, Ironbow 2, White Hot, Black Hot, Color 1, Color 2, Fusion, Rainbow, Glowbow, Sepia, Ice-Fire, Rain, and OEM Custom.
Another adjustable specification of this system is the reticle. You can choose from 6 digitally-controlled reticle patterns: Crosshair, Line Dot, Dot 4 MOA, Cross Center Dot, Cross, and No Reticle. Reticle color schemes can be changed as well.
Lens type is also an important consideration in choosing the right thermal scope. This system comes with Germanium objective lens with an objective focal length of 42mm, which is higher than most thermal imaging systems in the market. The Zeus 4 offers a FOV at 5.5×4.0 degrees, enabling you to detect targets with a wider viewing range. The lens is fitted with a 45mm eye relief component that makes for a more comfortable viewing experience.
The diopter can be adjusted within a range of +5 to -5, according to preferred image sharpness and clarity. Both the diopter and the lens focus are manually adjustable, giving you complete control over how you want to perceive your images.
In summary, Armasight has proven once more why they are one of the leading companies in producing thermal imaging scopes. The Zeus 4 is all about top-notch specifications and features—all packed in one compact, ergonomic thermal system.
