8km 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.

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

A pod is a short, streamlined nacelle section in which a piece of airborne equipment or a weapon is mounted and suspended from the fuselage or under the wing. They can be fixed (e.g. engine pods) or detachable (e.g. weapon pods). The addition of a pod can provide an aircraft with a function that it does not have on its own, and the addition of a pod usually requires the support of on-board electronics and consideration of the overall aerodynamics of the aircraft.With the development of aviation technology, airborne pod technology has also made great progress.

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.

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.

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.
