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.

The 10th edition of the Milipol Singapor 2024 exhibition commenced on April 3rd in Singapor. This exhibition not only serves as an ideal platform for armed forces, police, and related agencies to procure security and defense equipment but also provides a crucial stage for nations to showcase advanced defense technologies and exchange cutting-edge defense concepts.

In the technological wave of 2024, infrared camera photography, is quietly changing the way we perceive the natural world. This is not only a technological innovation, but also a profound empowerment in the field of biodiversity conservation and ecological research.

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

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.

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.

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.

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.
