Zeiss Night Vision
The Zeiss Victory 5.6x62 LT* NightVision uses the principle of residual light amplification. When darkness falls, moonlight, stars or a bright horizon nevertheless emit residual light that can be amplified by night vision devices. The objects observed reflect tiny amounts of this light, which are used by the Zeiss NV to make the object visible.
LotuTec® coating on the Victory NV Scope lenses works like a protective shield for the lens and raindrops literally roll right off the glass. The LotuTec® coating is very durable and resistant to abrasion so the lens surface can be cleaned easily without damaging the optics. The light transmission of the lenses is not affected by the additional protective coating.
A simple to use range-estimation reticle is provided in the Victory NV Scope. It is designed for metric units of measurement. Assuming you know the specific size of a target, you would simply bracket it between the lines in the reticle to determine the distance to the target.
