This MILSPEC USA PVS 14 Standard night vision monocular comes with a complete set of housing and lenses MILSPEC USA with improved anti-reflective coatings on front and rear lenses. 

Each monocular is assembled, purged, and tested one by one, meticulously, with precision tools. The PVS-14 monocular is the standard night vision unit used by most of the NATO armed forces. worldwide, to be approved by NATO they must pass some rigorous quality and durability tests.

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

All intensifier tubes may have some imperfection 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.

They are made of WP or white phosphorus, which is less straining on the eyes after prolonged use than the classic GP or green phosphorus. The difference between the PVS 14 PRO and the PVS 14 standard it is the quality of the housing and the lenses, in this one they are MILSPEC USA and in the standard they are MILSPEC Israeli. These are of better quality.
