Small -size X ray instrument for nondestructive testing of resolution ratio adjustable

The utility model provides a small -size X ray instrument for nondestructive testing of resolution ratio adjustable, it can wide application in fields such as electron, material, quality testing, archaeology, medical science. The utility model discloses a: plumbous glass, X -ray pipe, transformer, step motor, guide rail slip table, slider, image intensifier, camera lens, protection casing. Wherein, fix protection casing, aluminum pipe and transformer on the slider for the X -ray pipe can be realized reciprocating through sliding guide, changes the distance of X -ray pipe and testee, thereby satisfies the requirement of image resolution adjustable. Consider that X -radiation factor overall structure adopts metal totally enclosed design and light succinct, the convenient removal to fixed plumbous glass carries out secondary protection the improvement effectively safety protection measure on quick -witted case.
