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.

Why is it that infrared thermography can capture images in total darkness at night that we normally cannot see with the naked eye?Because everything with a temperature above absolute zero (-273°) emits infrared radiation. An infrared camera can convert the thermal radiation into a corresponding electrical signal, which is then amplified and processed to obtain a thermal image corresponding to the heat distribution on the surface of the object.

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.

Both plants, animals, humans, cars and objects emit heat. The defining characteristic of a thermal sensor is the detection of heat in response to small differences between thermal features in the image. So whether it's raining, sunny or completely dark, thermal imaging cameras provide clear thermal images. For this whole reason, thermal images characterized by high contrast are ideal for video analysis.Today, thermal imaging cameras are the monitoring solution of choice for nuclear power plants, substations, oil refineries and airports.

The differences between infrared thermography and low-light imaging are as follows:1. Imaging Principle:Infrared Thermography:It captures the infrared radiation emitted by objects and converts it into visible images. All objects above absolute zero emit infrared radiation, which can be detected and used to create a temperature distribution map, displaying the thermal image of the object. This technology does not require external light sources and can work in completely dark environments.Low-light Imaging:It relies on amplifying extremely weak ambient light, such as moonlight or starlight.

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

UAVs were initially used in the military field, and in recent years, the state has encouraged the use of UAVs in the industrial field, which has promoted the development of industrial-grade UAVs, and UAV optoelectronic pod products have gained rapid development under the policy dividend.The application of optoelectronic pods on drones is becoming more and more extensive, and they can be applied to public security monitoring, danger rescue, electricity, meteorology and agricultural plant protection.
