摘要

A capillary tube (1) e.g. for locating crystals in vacuum ultraviolet technology, comprises a number of elements (2) coaxial to the capillary axis. The reflecting inner surface of the capillary member, corresponds with the longitudinal rotational ellipsoid (3), where the focal point (4) lies on the capillary axis outside the tube.
