Night vision clip-on systems: technologies and features - buyer's guide

To perform various work, people actively use night optics. It does an excellent job and eliminates the inability of the human eye to see at night. The devices used are successfully combined with clip-on systems. The latter turn even daytime optics into an NV device and allow it to be used for its intended purpose. At the same time, it will not be necessary to reconfigure the equipment or zero the weapon, which will simplify the operation process as much as possible.

Main night vision clip-on scopes characteristics

NVDs from the clip-on category perform satisfactorily in use. Due to their many positive qualities, they are introduced into various industries to perform a particular job. Clip-on systems are most commonly used in combination with scopes. Such optics have become universal and is available not only to the military but also to civilians. The latter use it for hunting at night, which gives many new and incomparable experiences. To understand a little about the nuances of clip-on sights, you need to study their characteristics. This information will be helpful in the process of buying one of the models.

Basic Features:

• Dimensions. Most of the models produced these days have a minimum size. It simplifies the operation of optics and their transportation and storage at home. Most often, the length of clip-on sights varies between 150-180 mm, and the width and height are 75-100 mm. Sometimes there are also more compact models. At the same time, outdated clip-on sights often have larger dimensions than modern ones.
• Weight. This characteristic is one of the most important. The convenience of using optics in the field depends on it. It directly depends on the capabilities of the optics. In most cases, clip-on systems weigh about 1 kilogram. The most versatile models have more weight, and simple ones have a minimum.
• Screen resolution. This characteristic is one of the keys. It shows the capabilities of the display on which the image is displayed. The higher the value of this parameter, the clearer the picture will be, and it will be possible to see all its details.
• Multiplicity. This parameter indicates the possibility of enlarging the image by a certain number of times. The higher the value, the more distant objects can be seen through the scope. Most commonly, civilians use clip-on sights with magnifications up to 10x. Large values ​​of this parameter are used mainly by the military.
• Lens diameter. This indicator characterizes the size of the sight lens used to collect light rays. The larger it is, the brighter and better the visible image will become. On sale, you can find models with 25-100 mm diameter. At the same time, average indicators of 45-55 mm will be optimal for most users. In this case, the optics will be practical when working short and medium distances.
• Exit pupil diameter. This value is calculated. It is defined as the ratio of lens diameter to magnification. Higher values ​​of this parameter will make the sight work as efficiently as possible in conditions of minimal illumination.
• Removal of the exit pupil. This characteristic indicates the distance between the user's eye and the eyepiece of the sight, at which the maximum available field of view becomes visible. This figure can vary widely. Each user independently determines for himself the best option following personal preferences.
• Minimum focusing distance. The value of this parameter must be considered when it is required to use sight to observe a closely located object. It shows the distance at which one model can give the user good visibility. At the same time, manufacturers often indicate the maximum value of the focusing distance with an infinity sign.
• Field of view. This parameter indicates the ability to provide a view of a large area. The higher the value, the wider the area will be inspected. The maximum values ​​are essential when searching for an object of interest on the ground. In such a situation, it is possible to quickly review the surrounding area and find the thing of interest.
• Correction of diopters. People with good and bad eyesight exploit Clip-on. In the second case, the range of diopter correction will be necessary for users. It shows deviations from the zero value (100% vision) in one direction and the other, allowing you to compensate for eye problems. As a result, even a person with myopia or hyperopia sees well and does not experience discomfort during the operation of the optics.
• Battery life. Modern optics cannot work without an energy source. Most often, they are classic batteries or Li-ion batteries. Each model uses its resource differently. Because of this, the battery life changes. The larger it is, the longer you can operate the optics without recharging or replacing batteries. In this regard, most prefer to buy models with a maximum energy supply and minimum consumption.
• They are operating temperature range. Its limit values are usually 40-50°C below zero and 50-60°C above zero. Sometimes there are also extended temperature ranges, making it possible to use the sight in extreme conditions. For the sight to be used in almost any region, you must buy models with the most comprehensive possible temperature range.
• Housing material. This structural element protects internal parts from various influences. Therefore, it must be made of durable materials with a relatively low weight. All this will increase the reliability of the optics and reduce the likelihood of damage.
• The level of protection. Clip-on models are operated outdoors. Therefore, devices are exposed to environmental factors that harm most structural elements. To prevent this, manufacturers pay attention to such a parameter as protection (from water, ultraviolet radiation, mechanical stress, etc.). The higher its level, the more reliable and durable the optics will become.
• Cost. For many buyers, the most crucial feature of scopes is price. It depends on many factors and varies widely. Thanks to this, in each price segment, there are many models suitable for people with different financial capabilities.
• Possibility of shooting. Some modern models allow the user to shoot videos and take pictures. Thanks to this, it is possible to capture important moments of an event (for example, hunting). All created media files are saved to a memory card with a separate slot. Also, real-time video transmission becomes available if the device has a Wi-Fi module.
• GPS. GPS sensors complement many sights produced today. Their presence allows you to track the user's location and find him in case of unforeseen situations. This characteristic is beneficial for hunters, travelers, and lovers of wildlife. It allows you to control the movement of people and help them with various problems (for example, leaving a familiar path).
• Distance measurement. Some expensive models are supplemented with rangefinders. These devices make it possible to measure the distance to objects and use this information for more accurate aiming. Also, the presence of a rangefinder will allow you to determine the approximate height or length of various obstacles (hill, pond, etc.).
• Reticle pattern. Another critical component of any scope is the reticle. It can be different, ranging from a simple dot in the center to dozens of lines. A particular option is selected based on the needs of the user. In all cases, using the reticle allows for better aiming and adjustments as environmental conditions change. For night models, points and lines must be highlighted. Only in this case will they be visible in the dark.
• Durability. Almost all modern clip-on models work correctly for an extended period. This became possible due to control at each production stage and repeated testing for compliance with various parameters. Also, the durability is affected by the excellent quality of the components used in the production (made from modern materials with increased strength indicators).
