Have you ever tried to see in the dark? No matter how wide you open your eyes, if you were cloaked in darkness, all you could see would be darkness around you. However, consider being in a place where you were surrounded by darkness, yet you were able to see everything in the dark. It would be a wonderful gift. With the advancement of technology, sighting in the dark has been made possible with night optics. Night vision equipment has made it possible for human beings to see in the dark.
You would come across numerous kinds of night vision equipment such as night-vision goggles, thermal night vision, ITT night vision, night vision monocular and binoculars, and night vision digital cameras. The foremost thing that might occur to you would be that night vision equipment is the thing in spy movies.
Basics of night vision equipment
With suitable night vision equipment, you would be able to see a person standing nearly 200 feet away in complete darkness. Night vision equipment could work in two different ways based on the implemented technology inclusive of image enhancement and thermal imaging.
Image enhancement entails light particles (photons) gathered in small amounts. The amount of light would be inclusive of the lower portion of the infrared light spectrum. It would be pertinent to mention here that night vision equipment catches the light and amplifies it to the point where you could easily observe the image.
Thermal imaging entails technology making the night vision equipment operate by capturing the upper portion of the infrared light spectrum. The objects would emit light in the form of heat energy instead of light reflection.
Working of night vision binoculars
The optics used in the night vision binoculars would amplify the subsisting light. They would make the light evident to the naked eyes. They are immensely helpful for the infrared spectrum. Eminent and good night vision binoculars have illuminators for amplifying the present infrared light.
However, the things you would see through a night vision lens would appear greenish to your eyes, as your eyes do not see the objects directly. However, they would see their image made on a phosphor screen. The intensity of the amplified light or the performance of the night vision binoculars would be dependent on the conditions of the available light. It would be pertinent to mention here that the light situation and the power of the binoculars have an inverse relation. You would require a powerful infrared night vision if the light situation gets weaker and vice-versa.
Different kinds of night vision binoculars
When it comes to buying night vision binoculars, rest assured to come across numerous kinds of options made available in the market. The most popular kinds of night vision binoculars would be inclusive of the first generation, second generation, third, and fourth-generation binoculars.
First-generation night vision binoculars have the power to amplify existing light by an aspect of 1000. The second generation would work well under the crescent moon. Third and fourth generation binoculars would offer great results on dark and cloudy nights.
