Characteristics of night vision
Using intensified night vision is different from using regular binoculars and/or your own eyes. Below are some of the aspects of night vision that you should be aware of when you are using an image intensified night vision system.
Objects that appear light during the day but have a dull surface may appear darker through the night vision unit than objects that are dark during the day but have a highly reflective surface. For example, a shiny dark colored jacket may appear brighter than a light colored jacket with a dull surface.
Night vision does not present normal depth perception.
Fog and Rain
Night vision is very responsive to reflective ambient light; therefore, the light reflecting off of fog or heavy rain causes much more light to go toward the night vision unit and may degrade its performance.
This is a faint hexagonal pattern which is the result of the manufacturing process.
A few black spots throughout the image area are also inherent characteristics of all night vision technology. These spots will remain constant and should not increase in size or number.
* Do not be concerned if you see this feature-it is an inherent characteristic found in light amplification night vision systems that incorporate a microchannel plate in the intensifer.
