NIGHT VISION DEVICES

Night vision devices are divided in the 1st generation, 2nd generation, and digital devices. They can be monocular or binocular. These devices use the light gathered from the photons at night (moon, stars, or infrared light) and transform it into electrodes by use of photocathodes (usually supplied by batteries). The 1st generation devices are capable of intensifying the ambient light around 1000 times, while for the 2nd generation night vision devices this number is around 20 000 as well as they are smaller and provide brighter and sharper image. The modern digital night vision devices are performing close to the 1st generation devices, but may be acquired at a lower price and eliminate image distortion. The modern thermal cameras will allow you to spot temperature difference of up to 0.2C 300 meters away from the object and will be irreplaceable assistance in animal observation or elimination of sources of heat loss at your home.
