The price difference between the second-generation and third-generation night vision devices is usually large. Generally speaking, the price of second-generation night vision devices is between 20,000 and 50,000 yuan, while the price of third-generation night vision devices is generally above 50,000 yuan. The following is an analysis of the reasons for the large price difference:

1. Technology and material cost

Image tube technology: The third-generation night vision device uses more advanced image tube technology, such as gallium arsenide (GaAs) materials, etc., and its research and development and production costs are relatively high. In contrast, the second-generation night vision device usually uses S25 material, which is relatively low in cost.

Manufacturing process: The third-generation night vision device has more stringent and complex process requirements during the manufacturing process, requiring higher precision and quality control, which also increases the manufacturing cost.

2. Performance improvement

Image quality: The third-generation night vision device is significantly better than the second-generation night vision device in terms of imaging effect, resolution, sensitivity and target recognition ability in extremely weak light environments. It can provide clearer and more stable images and better meet the needs of professional users, so the price is also higher.

Working life: The surface of the anode tube of the third-generation night vision device is often plated with a lanthanum ion film to extend the service life, and it has better stability under different environmental conditions and can adapt to a wider range of environmental changes such as temperature and humidity. Its long service life and stability also make the price relatively high.

3. Application fields

Military and law enforcement needs: The third-generation night vision device is mainly used in military, law enforcement and other fields with extremely high requirements for night vision performance. These fields have strict requirements on the performance and reliability of the equipment and are willing to pay a higher price for high-performance equipment. Although the second-generation night vision device can also meet some military and law enforcement needs, its performance is not as good as the third-generation night vision device in some high-demand scenarios. It is more used in the civilian market and some cost-sensitive fields, and the price is relatively low.
