Abstract
The X-ray image microscope according to this invention comprises an X-ray absorption imaging unit having a glazing incidence mirror, and an electron imaging unit having an electron lens connected to the X-ray absorption imaging unit. A thin support film is provided on the boundary between the X-ray absorption imaging unit and the electron imaging unit. On the support film is formed a photocathode screen which emits photoelectrons in response to an incident X-ray. The X-ray absorption image of an X-ray which has penetrated a specimen, e.g. a living cell, is magnified by the X-ray imaging unit, and the electron image corresponding to the X-ray image is magnified by an electron lens. The magnified electron image is converted into a light image by a phosphor screen, and the light image is caught by a TV camera. In this way biological materials can be observed, magnified in their living states.
