Abstract
A probe head () of an NMR-MAS assembly has a stator () with an opening () receiving a rotor () which, in a measuring position, rotates at the magic angle to the Bfield. The stator is pivotable between the measuring position and a loading position of the rotor. A detection device () permits external, contactless identification of whether the opening of the stator is fitted with a rotor. The detection device has a light source (), from which light is introduced into a lower end (″) of a light guide (). The stator has a first bore (), in which a first light guide stump () is positioned such that, in the loading position of the stator, it produces an optical connection between a rotor inserted in the stator and an upper end (') of the light guide opposite the lower end.
