How to use low-light night vision goggles correctly?

1. Preparation before operation

Check the integrity of the equipment: Before use, carefully check whether the appearance of the low-light night vision goggles is damaged, such as whether the lens has scratches or cracks, whether the body has bumps, etc. At the same time, check whether the various adjustment buttons and knobs can work properly.

Install batteries or connect power: According to the requirements of the equipment manual, correctly install batteries or connect external power. Pay attention to the positive and negative directions of the battery to avoid damage to the equipment due to incorrect installation. If it is a rechargeable low-light night vision goggles, make sure the battery is fully charged.

Adjust the eyepiece and objective lens: According to the user's vision, adjust the eyepiece first. By rotating the eyepiece so that you can clearly see the reticle or the internal logo, this step is like adjusting the eyepiece of a telescope to ensure that the user can observe comfortably. Then, adjust the focal length of the objective lens so that the distant target can be clearly imaged.

2. Key points of operation during use

Hold or install the device correctly: If it is a handheld low-light night vision device, hold it steadily with both hands to avoid shaking that affects the observation effect. You can lean your arms on your body or other supports to increase stability. If it is installed on equipment such as helmets and firearms, ensure that it is firmly installed, and pay attention to the coordination of the device and your own movements during use.

Reasonably adjust the brightness and contrast: adjust the brightness and contrast of the low-light night vision device according to the intensity of the ambient light. In a dark environment, the brightness can be appropriately increased, but be careful to avoid excessive brightness that causes image distortion or halos. Contrast adjustment can make the difference between the target and the background more obvious and easy to observe. In general, adjust the brightness and contrast to a moderate position first, and then fine-tune according to the actual observation situation.

Avoid direct strong light: The low-light night vision device is very sensitive to strong light, and avoid strong light directly shining on the lens during use. If you encounter strong light, such as oncoming car headlights or strong flashlight light, you should immediately look away or temporarily turn off the night vision device to prevent the strong light from damaging the image intensifier inside the device.

Scanning observation method: Use scanning to observe instead of staring at one point for a long time. Because the human eye is prone to visual fatigue when staring at a target for a long time in a low-light environment, and scanning can expand the observation range and understand the surrounding environment more comprehensively. You can move your sight regularly from left to right and from top to bottom, focusing on areas where targets may appear, such as corners of roads, doors and windows of buildings, etc.

3. Maintenance after use

Cleaning the device: Use a clean, soft cloth to wipe the lens and body of the low-light night vision device. If there are stains on the lens, you can use a special lens cleaning fluid and lens paper to clean it, and avoid using rough materials to scratch the lens. At the same time, clean the dust and dirt on the body to keep the device clean.

Correct storage: Store the low-light night vision device in a dry, cool place, away from direct sunlight and humid environment. You can put it in a special equipment box or packaging box, and put a desiccant to prevent the equipment from being damaged by moisture. If it is not used for a long time, it is best to remove the battery to prevent battery leakage from corroding the internal components of the device.

Common low-light night vision devices on the market: four-eye night vision device GPNVG-18, binocular night vision device PVS-31, binocular monocular night vision device PVS-7, monocular night vision device PVS-14.
