Night vision equipment can be roughly categorized into three main groups:Spotting scopes - Spotting scopes are generally hand-held and can also be mounted on a weapon, they utilize a monocular (one eye) body. Since spotting scopes are handheld devices and are not worn on the body like eyepieces, they are more suitable when you want to take a more detailed look at a specific target and then return to normal observation conditions.Eyepieces - Although eyepieces can also be handheld, they are usually worn on the forehead.

When is it necessary to calculate the distance factor ratio and when is it not?

How to buy a good enough night vision device?Now, we start to share with you some dry facts to help people who wish to buy a night vision device to buy one that meets their requirements.Classification of night vision devices:First of all, Night Vision Devices (Night Vision Devices) are categorized into Infrared Night Vision (Infrared Night Vision), Laser Night Vision (Digital Night Vision) and Shimmer Night Vision (Image Intensifier). After testing these three types we can tell you with confidence that the Microlight Night Vision is the only night vision device worth buying.

Anti-drone can be categorized from a functional point of view into two parts: drone detection and detection and drone countermeasures.The main drone detection technologies are: radio-based drone detection, radar-based drone detection+, and optoelectronic-based drone detection.

In industry, the provision of reliable power is critical to equipment safety and personnel safety, and it ensures the smooth operation of motors, transformers, conductors, power cables, and other types of electrical installations.There are often a large number of switches, contacts, wiring, casing clamps and other components in the electrical equipment system, which cause abnormal overheating points due to poor contact, corrosion, internal abnormalities and other reasons, jeopardizing the normal operation of the equipment as well as the safety of the power supply, and leading to electrical fir

On February 4, 2024, the 2024 World Defense Show (WDS) opened in Riyadh, the capital of the Saudi Arabia.

When it comes to night vision devices, most people think of image intensification technology. In fact, image intensification systems are generally referred to as night vision devices (NVDs.) Inside the NVD is an image intensifier tube that can be used to capture and amplify infrared and visible light. Here's how an image intensification system works:A conventional lens called an objective lens captures ambient light and certain near-infrared light.The collected light is transmitted to the image intensifier tube.

Depending on their clarity and sensitivity, night vision devices are categorized into four generations - gen0, gen1, gen2, and gen3 (note that there is currently no gen4 for night vision devices).Gen 0 refers to other principles of construction of night vision devices (mainly infrared night vision devices) other than microlight night vision devices, the first time to use in the European theater of operations during the Second World War.
