Around the 1950’s scientists and engineers from the US Army discovered the first viable method for showing the faintest of light, know as electromagnetic radiation, that was not within the visible spectrum for the human eye. With this discovery began the journey to our modern day near daylight night vision devices. This enabled soldiers to fight as well during the night as they did in the daytime. “Own the Night” became the soliders new ability.
Darkness has always been an issue during the war, how do you fight an enemy you cannot see. Prior to the discovery of night vision technology, soldiers battled during the night with various primitive methods, including the use of fire, and more modern times, electric search lights.
But on the battlefield these methods were also a disadvantage , not only could they see the enemy but the enemy could see them, and what they were up to. Modern night vision googles make up for this by huge factors.
During the mid 60’s the clever people who first worked on night vision technology created what has become known as the first generation night vision device. This was a passive unit, and the first was know as a Starlight Scope, which could be used as a rifle scope. This was the first major practical use in the military of night vision units.
Over the years engineers and scientists continued on this technology to deliver the second, third, and now fourth generation night vision equipment, and they continue to come up with new ideas as research efforts pay off.

Ferranti International are renowned for making night vision goggles for the British Military. The most well known pair of Ferranti night vision goggles available today are the Nite-Op NVGS. These particular goggles are a more advanced version of their ANVIS night vision goggles which the British military used to rely on.
In fact the design of the Nite-Op is basically the same as the ANVIS although they have a much craggier mounting system and they provide the user with a wider field of viewing. Plus the lenses on these night vision goggles are much wider in terms of the diameter which provides the wearer with a lot more comfort when being worn.
Actually, all types of night vision goggles are very similar in that they will all contain certain components in them. The main components that you will find in any type of night vision goggles are as follows:-
1. Image Intensifier
2. Objective Lens System
3. Eye Lens System
But although all night vision googles contain these 3 main components within their manufacture, how they are created and then engineered will result in a difference in how effective the goggles really are. Although they are most commonly used to help a person improve their viewing capabilities at night they are now being used in helping with search and retrieval tasks.
When looking for a good quality pair of night vision goggles whether it be a pair of Ferranti night vision goggles or a pair made by another manufacturer such as Bushnell it is important that you learn as much about them as possible.
Certainly once you start reading up on the various models available you will find a lot of sites offering a short description along with a list of the various features that each model has to offer the wearer. By learning more about the various features on each model you will be better able to understand their capabilities and what the quality of the images are like. Therefore it is best to take your time learning as much as you can about each model prior to make any final decisions on which pair it is you wish to purchase.
