In addition to the technology, the devices can also be distinguished according to their type of build. Basically there are devices with monocular and binocular build types.
The binocular night vision devices can be further divided into two sections. On the one hand, there are devices with two objective lenses, which are also equipped with two light-intensifying processes. On the other hand, there are binocular devices which have two eyepieces but only one objective lens and thus only one light-intensifying process. These devices are more cost-effective and offer a more pleasant visual experience than monoculars, but they do not produce such a plastic image.
