Night Vision Scope
Night Vision works by amplifying ambient light available to the sensor, typically creating a green-hue image that can be viewed in near total darkness.
Night Vision light sensitivity is measured in lux, the smaller the number the better.
Lux is defined as the amount of illumination created when one lumen is distributed over an area of one square meter.
PARD Night Vision devices are sensitive down to .001 lux. This is roughly equivalent to being able to see a lit match on the 50-yard line of the Superbowl when sitting in the top row of the stadium.
Night Vision technology improves target identification, while Thermal technology improves detection.
Night Vison operates effectively when looking through glass.
