Night vision goggles NH9X DETAIL4

Eyepiece adjustment

Choose a target with moderate ambient brightness and adjust the eyepieces without opening the objective lens cover. As shown in Figure ③, turn the eyepiece handwheel clockwise or counterclockwise to match the vision of the human eye. When the clearest target image can be observed through the eyepiece, the eyepiece adjustment is complete. When different users use it, they need to readjust according to their own vision. Push the eyepiece toward the middle or pull the eyepiece outward to change the distance of the eyepiece.

 

Auto Mode

The automatic mode is different from the "IR" mode, and the automatic mode starts the environment detection sensor. It can detect environmental illuminance in real time and work with reference to illumination control system. Under extremely low or extremely dark environment, The system will automatically turn on infrared auxiliary lighting, and when the environmental illumination can meet normal observation, The system automatically closes "IR", and when the ambient illumination reaches 40-100Lux, The whole system is automatically shut down to protect the photosensitive core components from damage by strong light.
