Micro-focus X-ray generator

The utility model discloses a microfocus X-ray generator which comprises a protective sleeve body, one end of the protective sleeve body is conically shrunk to form a light outlet, an X-ray generator body is arranged in the protective sleeve body, a conical refraction lens is arranged at the conically shrunk position, and the X-ray generator body and the refraction lens are in axial butt joint. The X-ray generator body is provided with a light outlet, a lens is arranged at the light outlet, arc-shaped notches used for refracting light are formed in the bottom of the X-ray generator body and the bottom of the refraction lens, and the top of the X-ray generator body extends to the bottom of the refraction lens and is attached to the arc-shaped notch in the bottom of the refraction lens. According to the X-ray generator, light rays generated by the X-ray generator body are refracted by the arc-shaped notches and then are intensively emitted from the middle part, so that the scattering of the light rays is reduce
