Generally speaking, the service life of the core component of the third-generation night vision device, the image intensifier, is usually around 10,000 hours to 12,000 hours. If calculated based on 1,000 hours of use per year, its service life is approximately between 10 and 12 years. The following are some factors that affect the service life of the third-generation night vision device:

1. Use environment

Temperature: In extreme temperature environments, such as long-term high or low temperature environments, the aging of electronic components and optical components inside the night vision device may be accelerated, reducing its service life. It is generally recommended that the third-generation night vision device be used in a temperature range of -40℃ to +50℃.

Humidity: A high humidity environment may cause moisture and mold inside the night vision device, affecting its performance and life. Therefore, after using it in a humid environment, the night vision device should be dried in time and stored in a dry and ventilated place.

Sand and dust: If it is often used in a harsh environment with a lot of sand and dust, sand and dust particles may enter the night vision device, scratch the optical lens, block the heat dissipation channel or affect the normal operation of electronic components, thereby shortening the service life.

2. Frequency and duration of use

Continuous use time: Long-term continuous use will cause the image intensifier, battery and other components of the night vision device to continue to work, generate heat accumulation, and accelerate the aging of components. Therefore, during use, you should avoid long-term continuous use and take a proper rest to extend its service life.

Number of uses: Frequent use will increase the wear and aging of the night vision device. For some professional users who need to use night vision devices frequently, they should use and maintain them in strict accordance with the operating procedures to reduce damage to the equipment.

3. Maintenance

Cleaning: Regularly clean the lens, housing, display and other components of the night vision device. You can use a clean and soft cloth to wipe gently, and avoid using organic solvents or rough materials to wipe, so as not to damage the optical components or the surface of the housing.

Battery maintenance: Proper use and charging of batteries, avoiding overcharging and over-discharging, can extend the battery life and the overall service life of the night vision device. When the night vision device is not in use, the battery should be removed in time to prevent battery leakage from damaging the device.

Regular inspection: Regularly inspect the night vision device, including appearance inspection, optical performance inspection, electronic function inspection, etc., to promptly discover and deal with potential problems and ensure that the device is in good working condition.
