Night Vision Optics
Night Vision Devices are observational devices that can convert image invisible in the dark into a visible or just enhance brightness and contrast. All standard night vision devices consist of a lens, amplifying device, image receiver and a monitor. Night vision devices differ in their type of use and appearance. They can be active-impulsive, active or passive, and produced as a monocular, binocular or goggles. Today customers choose not only optical but also digital night vision devices. This technique is the next step in tracking technology, as it frees a man from having a long stare into the darkness - image is displayed on the monitor screen. You do not need to remain motionless for a long time in an uncomfortable position - you can connect the device to the digital media and record the whole session of observation.
