Product Description:

DT-NH81X is a new product based on the latest optoelectronics technology. It uses high-performance second-generation/third generation image intensifier. It has the characteristics of excellent performance, small size, light weight, clear image, simple operation, high performance-price ratio, and the magnification can be changed by replacing objective lens (or connecting multiplier lens). The product can be connected with digital cameras, cameras and video cameras. It can be used with gun sight card or alone. The night vision instrument has built-in infrared auxiliary light source and automatic strong light protection system. This product has strong practicability and can be applied to military observation, frontier and coastal defense reconnaissance, public security surveillance, evidence collection, customs smuggling, etc. in the night without lighting. It is an ideal equipment for public security departments, armed police forces, special police forces, and guard patrols.

 

1. The appearance of the product is compact and delicate. The fuselage is made of all metal. It is small in size, lightest in weight and high in strength.

2. Skillful design and high-quality image tube are adopted to maximize the cost-performance ratio of products.

3. Good optical quality, clear imaging, high brightness, uniform brightness throughout the observation range.
