15km Laser Rangefinder Binocular-manufacture,factory,supplier from China

Laser rangefinder (Laser rangefinder), is the use of modulation of a certain parameter of the laser to achieve the distance measurement of the target instrument.

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.

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.

To understand the principles of night vision, it is necessary to know something about the principles of light. The amount of energy in a light wave is related to its wavelength: the shorter the wavelength, the higher the energy. In visible light, violet light has the highest energy, while red light has the lowest. Adjacent to the visible light spectrum is the infrared spectrum.

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.

Photoelectric pod technology and its pods are an important part of photoelectric reconnaissance and warning technology and its equipment, but also the core equipment of unmanned aircraft reconnaissance, which will fill the role of tactical reconnaissance of specialized manned aircraft, for which various countries are vigorously developing photoelectric pods for various purposes.

From January 16 to 18, 2024, the 25th Middle East (Dubai) International Security Equipment and Technology Exhibition (Intersec Dubai) in Dubai World Trade Center (DWTC) concluded perfectly, 1,000 exhibitors from more than 60 countries and regions to display their latest products and technological achievements in the field of security.Jovstar with “AI + security” as the core, relying on artificial intelligence, cloud computing, big data and other new generation of information technology, to the global customer focus on portable multi-functional thermal imaging camera, gun sights, micro-light ni

Infrared night vision device is the use of photoelectric conversion technology of military night vision device. It is divided into active and passive two kinds: the former with infrared searchlight irradiation target, receive reflected infrared radiation to form an image; the latter does not emit infrared, relying on the target's own infrared radiation to form a “thermal image”, so it is also known as the “thermal imaging camera”.Visible light at night is very weak, but infrared light, which is invisible to the human eye, is abundant.

In order to carry out high-quality wildlife monitoring work, recently, the staff of the Forestry Bureau in-depth nature reserves to set up a number of night vision devices, at the same time will be set up in the early night vision devices, and screening of pictures, video data for research and analysis.
