X-ray examining device |
摘要 |
An X-ray examining device comprises an optical aperture including adjustable sector-like laminations. The laminations are rotatable about axes perpendicular to the optical axis. The edges of the laminations are adapted to the optical system so that proper imaging is maintained in the case of a comparatively small opening of the aperture.
