The image intensifier can improve the brightness of the image and convert the invisible X-ray image into the visible image.
Image intensifier tube is the core component of image intensifier. Its structure is encapsulated with input screen, focusing electrode, accelerating electrode, output screen and ion pump in the vacuum glass shell.
The main function of input screen is to convert X-ray into electronic image; the function of electrostatic lens is to focus electron beam; and the function of output screen is to convert enhanced electronic image into visible image shell. The function of output screen is to support the input screen, output screen and the electrodes in the tube in a fixed position and maintain the vacuum in the tube.
