Night vision binoculars are an optical instrument that amplifies any small amount of existing light before sending it to our eyes to help users to see something in completely dark or in very low light. They were first introduced during Second World War and played a major role during Vietnam War also. Now they are available for civilian users also where they are used for a variety of purpose like hunting, hiking, boating, surveillance after dark.

It will help you to understand the device better. Afterall you are going to invest your hard earned money into it. So, doing some research beforehand can save you some money and it can also help you in the long run.
Let’s get started:-
How does Night Vision work?
Night Vision Device works on the basic principle of capturing any small amount of light then amplifying it. But the problem is there is no technology available today which can amplify light. So what we do we first turn light into electricity, after that we amplify/boost electricity, and then again we turn that amplified electricity into the light.
- First, a small amount of light enters into the front
- Now in the second step, light strikes a photocathode which converts photons (light is made of photons of all colors) into electrons.
- In the third step, these electrons are amplified with the help of photomultiplier (Microchannel plate).
- In the last step, those multiplied electrons hit the phosphor screen which creates the tiny flash of light (photon).
Why is the resulted image Green?
You must have noticed in movies or games that view through night vision device is green. Do you know why?
Because our eyes are more sensitive to green light, we can easily look at green screens for more period of time without any problem. That is the reason why in 4th step (above) phosphors on screen are deliberately chosen to make a green picture.
How much technologically advanced they are from their older version?
Over the year, Night vision technology has drastically evolved as Generation1, 2, 3. Each Generation is more advanced than the older one and also more expensive than the other. Here is a quick guide to that,
This is the night vision that was first introduced in Vietnam War. They are the least expensive with some basic technology as compared to Generation 2 and Generation 3. They employ a photo vacuum tube with a photocathode which results in a maximum range of 80yds. They have infrared illuminator built in which works great in the dark area.
The user should take note that, there is two variety of Generation 1 devices available in the market today. Some fake manufacturer uses a low-grade intensifier tube in their night vision device to lower the price of the device, stay away from them. Always look for top brands like Bushnell, Armasight, ATN and Night Owl. They are a massive brand in the field of night vision and thermal imaging. Their device might be little pricier than others but you can be sure you are buying a quality product. Most civilian, hunters, night observer prefer Generation 1 device, they are affordable and have decent quality but if money is not a problem then you can surely look for Gen 2.
These are more advanced than Generation 1 also more expensive. Generation 2 device use microchannel plate (MCP) to amplify the electrons. They are very good in low light condition. They amplify the light more than 20000 times which results in a maximum range of 350yds in a full moon. They have better resolution, longer battery life and life expectancy of about 4500hrs. If you are passionate about your work then these night vision device from Generation 2 is right for you.
Generation 3 devices are the most advanced and most expensive among all three generation. They use a strong chemical known as gallium-arsenide for the photocathode and a microchannel plate. In fact, they are so powerful that in some European countries they are restricted to government departments and military only. Although, they give the best performance, great battery life, and higher resolution all these come at great price. Cheapest night vision Generation 3 device costs more than $5000 today.
Note: – We are not covering any Generation 3rd night vision device in a list given below because they are so expensive that it is against our website policy. Here on “Telescopefever.com”, we review only those device which is easily affordable to common people. If indeed you are searching for Gen 3 device, we highly recommend the ATN brand.
Night Vision Device Buying Guide
Here are some tips and features that you must consider before buying your first Night Vision Device.
Size, Weight, Magnification, and Environment.
When it comes to choosing a right night vision device size, weight, magnification and the environment you are going to use the device are the major factors you should take into consideration before making a buying decision. Let’s say you are going to use the device in dense forest where it is impossible to see anything beyond certain distance then there is no need to spend extra money on higher magnification device. Same way, if you are planning to use your device from a static position, then no need to worry about size and weight of the device but if you are planning on being mobile, consider a lightweight and small device which you can carry around comfortably when on the move.
Let’s say you are in a completely dark area where not even a small source of light is available (ex-cave). There, IR illuminator in your night vision device can help you to see. They project the beam of infrared light which is then picked up by binoculars optics to allow the user to see in the complete darkness.
Review the Gain and Resolution.
Another thing to consider in your night vision device is the gain. Gain is the relative level of light you will see when looking through the device. In common terms also called resolution. Greater the magnification of the lenses, worse resolution or gain you will get. Always go for highest resolution device available in your budget.
If you are planning on using your night vision device on a rainy day or in a bad weather, always look for waterproof binoculars. They have O-ring sealed that prevents any small amount of water or moisture to enter into the device.
Binoculars tend to fog up from inside when moving from one temperature to another. To counter the problem manufactures use gases like Nitrogen or Argon and purge them inside the tube to save the device from internal fogging. Always look for that Fogproof device.
Best Night vision Binoculars Reviews 2017
1) Bushnell Equinox Series 6L Night Vision Z Digital Binocular
Objective Lens: 50mm
Tripod Mount: Yes
IR Illuminator: Yes

The device also features a 4x magnification that works great for daytime viewing where light is sufficient but during night at full 4x magnification quality seriously degrade and image resolution gets poorer, up to 2x its OK. In our opinion 4x at night is just a marketing gimmick.
Equinox Series 6L also boasts a unique design where the right objective aperture is dedicated for binocular viewing whereas left objective aperture house a built-in infrared illuminator. Always turn on your infrared illuminators during the night to increase clarity and visibility of target and don’t forget to turn it off during daytime to save some battery.
