Abstract
For observation of structures, for example of welding seams, within a cavity body, an optical system is provided, which is adapted to be introduced into the cavity body through an opening of reduced diameter. This optical system comprises two boroscopes having parallel shafts and bent off heads for illumination and observation. In a first position the heads are located antiparallel side-by-side and permit the introduction of the optical system through the opening. In a second position the heads are spread and form a base distance in the hollow body to illuminated the structure to be examined at an angle essentially different from the angle at which this structure is observed.
