Q1: What is an Image Intensifier Tube?
A: An Image Intensifier Tube (IIT) is a key component in night vision devices that amplifies low light from the environment to create a visible image, enabling clear vision in dark conditions. The tube works by collecting and enhancing light from moonlight, starlight, or other sources to provide users with amplified images in near darkness.


Q2: What types of Image Intensifier Tubes are available?
A: Ireeda have Gen 2/Gen 2+/Gen 3 image intensifier tubes,now Ireeda has over 300 pcs Gen 2+ image intensifier tubes and over 100 pcs Gen 3 Image intensifier tubes, so you can get your image intensifier tubes much more earlier than others suppliers.
