The AETERNUS binocular NVGs from the American brand Low Light Innovations that offers a revolutionary night vision system that redefines industry standards with incredible features and performance.

The binoculars are powered by a single CR123 battery, the AETERNUS from Low Light Innovations stands out for offering us a greater battery capacity. The brand's developers removed the IR illuminator from the binoculars, which helps extend the battery life up to 40 hours.

The weight is also one of the strong points of this binocular, With only 535 grams of weight (without battery). According to the manufacturer, the AETERNUS binoculars feature the most durable and user-friendly fixed housing on the market, and it has also improved structural integrity by providing us with a waterproof system.

The binoculars are submersible up to 18 meters (60 feet) what makes it suitable for amphibious operations. It has a focus range of 9.8 inches to infinity, a field of view of 40 degrees, and an interpupillary adjustment of 51 to 73 mm, the AETERNUS stands as the pinnacle of the optical excellenceIts compatibility with MX-10160 optics, PVS-14 eyepiece and objective further enhances its functionality.

This unit comes mounted with MILSPEC glasses from the USA, but other types of lenses can be mounted to reduce costs (OE), or RPO lenses, which are lighter but at a higher price.

Each binocular is assembled, purged, and tested one by one, meticulously, with precision tools. They must pass a rigorous quality and durability tests.

Among many other tests, they are subjected to drop tests to meet MIL-STD-810G standardsThis consists of 26 falls from a height of 1.22 meters (4 feet) onto concrete.

All intensifier tubes may have some imperfections in the image represented by spots of less than 0.3mm, generally there are only one or two visible imperfections, but these do not affect vision since it simply blends with the image we are viewing.

The FOM (Metric figure) is a simple way to calculate the performance of a viewfinder, it is easily calculated by multiplying the resolution x the noise of the image we see through the viewfinder. The higher the FOM, the better the quality of vision.

They have Auto-Gating, this technology allows the device to automatically adjust the amount of light amplification in real-time to adapt to changes in ambient brightness. This feature is particularly useful in situations where there are intense light sources, such as vehicle headlights or urban lights, that could dazzle the device and affect image quality. This helps maintain a clear and sharp image without compromising the user's vision in variable lighting environments.

The NVT come with a 2-year warranty for manufacturing defects, while the ECHO and ECHO + come with a 7-year warranty for manufacturing defects.

They are available in WP or white phosphorus, and GP or green phosphorus.
