Product Details

The night vision device has a built-in infrared auxiliary light source and an automatic anti-glare protection system.

It has strong practicability and can be used for military observation, border and coastal defense reconnaissance, public security surveillance, evidence collection, customs anti-smuggling, etc. in the night without lighting. It is an ideal equipment for public security departments, armed police forces, special police forces, and guarding patrols.

The distance between the eyes is adjustable, the imaging is clear, the operation is simple, and it is cost-effective. The magnification can be changed by changing the objective lens (or connecting the extender).

Night vision goggles NH9X DETAIL5

Objective adjustment

The purpose of objective lens adjustment to see clearly at different distances. Before adjusting the objective lens,Please adjust the eyepieces first according to the aforementioned method. When adjusting the objective lens, please select a darker environment. As shown in Figure ④, open the objective lens cover, aim at the target, and turn the objective lens focusing handwheel clockwise or counterclockwise until the clearest environment image is seen, and the objective lens adjustment is completed. When observing targets at different distances, the objective lens needs to be adjusted again according to the aforementioned method.

Infrared mode

When the ambient illuminance is very low (full black environment), and the night vision device cannot observe a clear image, you can turn the work switch clockwise to another gear. the system enters the "IR" mode. At this time, the built-in infrared auxiliary lighting of the product is turned on to ensure normal use in a completely dark environment. Note: In the infrared mode, if you encounter similar equipment, it is easy to expose the target.
