Abstract
Miniaturized spectrometer in the form of a probe for determining ingredients of a gaseous or liquid fluid with a light source and a spectrometer, at least one measurement beam, and at least one reference beam. Light from the light source is optionally fanned out and focused, by at least one optical lens, in an essentially parallel beam. At least one measurement beam is passed through a light transparent window from the probe into the fluid being investigated and through an additional light transparent window back in to the probe, and at least one reference beam is guided in the probe interior. A collecting optics device, comprising at least one lens, diverts the beams to the impingement point of the light guide or the inlet of the spectrometer, and a beam selector in the area of the collecting optics device passes through one of the partial beams and interrupts all the others.
