The composition and working principle of the image intensifier

Image intensifiers consist of input surface, photocathode, cluster electrode, anode and output surface in a vacuum state. As image intensifier converts x-rays, the photoelectrons accelerate through high pressure and image on the output surface via an electron lens cluster consisting of a cluster electrode and an anode.
Japanese Toshiba company, Thomson of France company production of 9 inches and 12 inches X line image intensifiers, its structure is, in large diameter vacuum tube, set up an input conversion screen and photocathode, there is a composed of electron lens focusing electrode and an output screen, when the X-ray projection in the enhanced tube input end face.
X-ray photons through the input window into the tube, absorbed by input switch panel, the energy is converted into visible light photons, and causes the photocathode emit electrons, these electrons are accelerated electron lens and converge to the output on the screen, and on the output end to form a corresponding to the input X-ray image has the enough brightness of visible light image.
Our image intensifiers can serve your different needs.
