The function of image intensifier tube in image intensifier analog camera is to enhance the weak visible image and make the image become a vacuum electronic device of bright visible image. In the image intensifier analog camera and the image converter of the image intensifier analog camera, when the external radiation image is imaged on the photocathode, the photocathode emits electrons. After the electrons are accelerated or focused and accelerated by the electron lens, the image intensifier analog camera is bombarded to produce a brighter visible image.
In 1934, holster and others made the first infrared image tube. When working, the voltage between the plane cathode and the flat screen is increased, and the cathode is very close to the screen. This is a near focus system. Since then, electrostatic focusing and electromagnetic focusing imaging systems have been applied to image intensifier analog camera.
Newheek has high voltage power supply for image intensifier analog camera.
