What is a Night Vision Scope?
How does a Night Vision Scope work?
Night vision rifle scopes are devices that enhance vision at night. Human eyes are greatly limited when it gets dark and the best night vision scopes make up for this limitation by applying appropriate technology that illuminates dark areas. The electro-optical element within the night vision scope enhances existing light by capturing ambient light, then use intensifiers to amplify it by thousands of times. The intensifiers are also responsible for improving the clarity and brightness of the image to be created. The ambient light comes from the moon, stars or sky glow. Light enters the goggles through an objective lens and hits a cathode, which is powered by a high power load. The charged energy then passes through a vacuum, at a high speed, and strikes a phosphor screen. This is where the image is focused.
The image one sees is not a “real object” but an enhanced electronic image that forms on the phosphor screen which is a component of the night vision riflescope. This is why the image appear green which is one of the color shades that the human eye perceives better than others. The phosphor screen of the scope has a limited lifespan but it should be able to last thousands of hours.
Other devices that use a similar technology include monoculars and cameras.

Types of Night Vision Scopes
Generation 1 (Gen 1)
Generation 2 (Gen 2)
Generation 3 (Gen 3)
Third generation night vision scopes are an improvement on second-generation scopes. They deliver great quality images thanks to the use of special chemicals and intensifier technology.
The intensifier of a Gen 3 night vision scope contains a gallium arsenide photocathode. This extra component increases the number of electrons that reach the phosphor scope screen. Gen 3 scopes are not readily available and they are very expensive as well. The best Gen 3 night vision scopes are designed for use in highly professional assignments.
Generation 4 (Gen 4)
Choosing the best Night Vision Scope
How much you have to spend will also determine the night vision scope that you can get. The cost of the best night vision scope is determined by its features and as such, if your budget is low you may have to forgo some of the impressive features that make a night vision scope great such as a powerful intensifier. Higher generation technologies scopes are more expensive than their lower generation counterparts and this is something that you need to bear in mind when shopping for the best gun scopes. If a scope is beyond your purchasing power and you don’t want to compromise on the features, you can decide to rent one for the moment as you raise the funds to buy your dream night vision scope.
The clarity of a night vision scope is its resolution in low light conditions which is very important in tactical operations and hunting. If you are not able to identify your target through the scope it means that the clarity of the scope is low and vice versa. The resolution of the best night vision scope is measured in lines per millimeter (LP/MM). A higher LP/MM will result is clear images and this increases the chances of succeeding at whatever you are doing at night.
Weight & Design
Bigger night vision scopes come with better vision optics as the scopes have enough components on the inside. This results in higher magnification which comes in handy when hunting small game in an open range. However, if you are hunting in tight spaces, you will need a lighter and ergonomic night vision scope that will not be difficult to carry around. Bulky scopes are not ideal in this situation as they will be difficult to aim and this greatly reduces your chances of making a successful shot.

How to mount a Scope
Mounting a scope is another thing that you need to learn to do if you want to use your rifle properly. A poorly mounted scope will result in a lot of frustration as you will not be able to aim at targets properly and most of your shots will be unsuccessful. Night vision scopes are mounted differently and with different materials. Some scopes, however, can only be mounted on specific guns and this is another thing you need to be aware of.
Scopes can be mounted using clips or screws. Scopes mounted with clips are easy to remove while those mounted with screws are sometimes difficult to remove. Follow the instructions explained in the manual before you mount the scope. Even if a scope is familiar to use, read the installation instructions carefully so as not to make mistakes that may lead to the scope getting damaged.
