The invention relates to spectrometer measuring heads (12) for analysing characteristic variables of liquid, pasty or solid substances for optical spectrometer systems. Said measuring heads are characterised, in particular, by their long-term stability, low maintenance and simple production. A rotationally mounted mirror (I) and at least one source of optical radiation (2) or a device for uncoupling optical radiation are arranged in a housing (6) in such a manner that the optical radiation is incident, by orientating the rotationally mounted mirror either on a reference body (3) in the housing or on the substance (14) that is to be analysed via a window (7) of the housing. The mirror is mechanically coupled to a drive (4) or a bending beam and as a flexing resonator in the housing. At least one fibre optic light guide (5) is arranged in the housing in such a manner that at least one part of the optical radiation reflected or transmitted by the surface either of the reference body or of the substance that is to be analysed is injected into the fibre optic light guide. Advantageously, the source of optical radiation in the spectrometer measuring head is integrated as an illuminant making it possible to illuminate the substance or the reference body with low losses.
