Night vision scope is a device used to enhance observation and aiming capabilities at night or in low light conditions. The following is a brief introduction:

Working principle

Low light night vision technology: The image intensifier is used to amplify and enhance weak natural light or starlight, so that the target can be clearly observed under low light conditions. For example, the Onick cs-55 low light scope uses a super second-generation image intensifier, which can be used for night field operations under low light conditions of 10⁻³ lux.

Infrared night vision technology: The active infrared scope emits infrared light to illuminate the target, and then receives the infrared light reflected by the target to form an image, thereby achieving night observation and aiming. Thermal imaging scopes use the infrared radiation emitted by the target itself and convert it into a visual thermal image, thereby accurately identifying and locating the target. They can work without external light sources, such as the onick cs-65 infrared thermal imaging night vision scope, which is equipped with a high-sensitivity thermal imaging detector and can work in a variety of complex environments.

Main types

Low-light-level night vision scopes: such as the 5x low-light-level night vision scope of Ditai Optoelectronics, which has excellent low-light detection capabilities and can be equipped with an external auxiliary light source to enable the infrared fill light function, which is suitable for sniping missions in low-light environments such as cities.

Infrared night vision scopes: including active infrared scopes and thermal imaging scopes. Active infrared scopes, such as the first-generation night vision scope of the 69-type 40 rocket launcher, consist of an infrared headlight and a scope, but are easy to expose the target and consume power quickly. Thermal imaging scopes are widely used in military, law enforcement, hunting and other fields due to their ability to capture the infrared radiation imaging of the target itself. For example, the Onick CS-55 infrared thermal imaging night vision scope has functions such as multi-channel display and image enhancement algorithm, which can realize long-distance search, accurate identification and shooting.

Holographic scope: Based on the principle of laser diffraction, such as the Onick Optical holographic scope CS-65, it has the characteristics of light weight, small size, low power consumption, and accurate imaging without parallax. It can be adjusted in multiple stages of brightness and is designed with day and night mode. It can be used with night vision devices at night.

Performance parameters

Magnification: determines the image size of the target in the scope. Common ones are 3x, 4.5x, 5x, etc. For example, the magnification of Onick Super Second Generation CS-55 low-light scope is 3x, and the magnification of Onick Optoelectronics 5x low-light night vision scope is 5x.

Objective aperture: A larger objective aperture can collect more light and improve the brightness and clarity of the image, such as Onick The objective lens diameter of the second-generation CS-55 low-light scope is 55mm.

Field of view: refers to the range that can be observed through the scope, generally expressed in angles, such as the field of view of the Onick CS-70 night vision scope is 11°.

Resolution: affects the details and clarity of the image, which is more important for thermal imaging scopes and low-light night vision scopes. For example, the Onick CS-55 infrared thermal imaging night vision scope is equipped with a 384*288, 12μm high-sensitivity thermal imaging detector, which can provide clearer images.

Exit pupil diameter and exit pupil distance: The larger the exit pupil diameter, the better the observation effect under low light conditions; the exit pupil distance affects the comfortable observation distance between the user's eyes and the scope. For example, the exit pupil diameter of the Onick second-generation CS-55 low-light scope is 5mm, and the exit pupil distance is 45mm.

Application fields

Military field: It is an important equipment for the army in night combat, reconnaissance, sniping and other tasks. It can help soldiers accurately find and aim at targets in the dark, improve combat effectiveness and survivability. For example, the Onick CS-70 night vision sight is equipped to the Italian Navy Special Forces.

Law enforcement department: During night patrols, arrests, counter-terrorism and other operations, the police can better monitor and respond to potential threats with the help of night vision sights to ensure public safety.

Hunting activities: Hunting enthusiasts can use night vision sights to find prey more easily at night, improve the success rate of hunting, and also increase the safety of the hunting process.

Outdoor adventure: In outdoor adventures, when encountering night environments, night vision sights help explorers observe the surrounding terrain, animals, etc., providing convenience and protection for adventure activities.

Security monitoring: It can be used to monitor important places, border defense lines, etc., enhance monitoring capabilities at night or in low-light environments, and detect abnormal situations in a timely manner.
