When you think of night vision the first thing that comes to mind is most likely a cool thing that you see in spy movies or something that the army uses on their top secret missions. The catch is that night vision technology is not all that high tech or just available to the operations of the government or in the dream of Hollywood.
Night vision works by collecting the small amounts of light that are still available even in the darkest of rooms there is always some kind of light available which night vision equipment takes and enhances giving some more ability to see everything in the room. The scientific wording of night vision is taking light on lowest end of the light spectrum and enhances those light particles to take them into the higher end of the light spectrum making them more visible to the human eye to use them to illuminate the room or surrounding area.
The high end light particles then allow the user to use thermal imaging which uses the heat generated by the body or other things that generate heat. All of the low spectrum light and the light from heat combine to allow the night vision products to work. Night vision has many uses and if you are in the market for night vision goggles, or thermal night vision goggles, there are plenty of options available on www.spyassociates.com to meet your night vision needs or any other surveillance product you may need.
