From ancient times to the present, night warfare has always been an inseparable topic in war. The reason why the army chose to launch an attack at night is that people have very poor visibility at night, and it is not easy to be detected, which can cover the combat operations to the greatest extent. In modern information warfare, it is very important to take the initiative to grasp the development of the battle situation. The convenience, speed and accuracy of information acquisition are very important. Observation during the day has many advantages. It can be realized by the human eye at close range and the long-distance technology is relatively mature. It relies more on various night vision technologies, so the technical research and development and application of night vision devices in individual observation and sight systems is particularly important. After the emergence and popularization of night vision goggles, the benefits of strong armies taking the initiative to attack at night have greatly increased, and they have even created an overwhelming battlefield advantage of one-way transparency at night.

Recently, Shenzhen Dongdi Optoelectronics Co., Ltd. launched the DB2021/DB3021 military binocular binocular helmet-mounted low-light night vision device (handheld).

product description

D-B2021 and D-B3021 are compact and lightweight binocular night vision devices that can be used flexibly. The magnification is 1 times, which provides users with a wide observation angle and space, and can judge the actual distance of the target faster. The advanced dual-channel design utilizes two high-performance image intensifier tubes to provide clearer images in dark environments. Watch with both eyes, protect the eyesight, even if you use it for a long time, you will not feel eye fatigue. The product has a wide range of applications and can be used for night field observation, night fishing, forest fire prevention, home security, night walking and driving, etc. It is an ideal device for outdoor night vision.

Features

●Waterproof and dustproof IP67: The device can work normally for 1 hour under 1m deep water

●Direction-sensing automatic switch: When the device is not needed temporarily, you can press a button on the helmet to lift the device up to the top position and then let go, and the device will automatically turn off at this time. When you need to continue to use it, press the same button to put down the device to the observation position, and the device will automatically return to work.

Zero consumption in standby: When not in use for a long time, the battery will not lose power when placed in the battery holder

●Battery cover spring embedded: It can better contact with the battery and the spring is not easy to be damaged, and it is easier to twist the battery cover.

●The helmet can be adjusted freely: the helmet device can be adjusted freely according to the size of the head of different users.

●Military multi-layer coating standard: The ultra-broadband multi-layer anti-reflection coating can suppress the broadband reflection on the glass surface of the lens, reduce the loss of light, and allow more light to pass through the lens to obtain a better observation effect.

●Automatic brightness adjustment: When the brightness of the surrounding environment changes, the brightness of the image we see from the night vision device does not change, which can ensure a stable observation effect and protect eyesight.

●Anti-glare light protection: When the surrounding light intensity exceeds 40Lux, the power of the device will be automatically turned off within 10 seconds to prevent damage to the image intensifier.

●Low battery indicator: When the battery is low, the green indicator light at the edge of the green phosphor screen can be observed flashing through the eyepiece.

●A separate infrared intensifier can be selected to enhance the effect of night use and expand the scope of application
