Abstract
In an instrument for spectral measurement in the bloodstream, the light-guide probe is developed with a diameter of, at most, 0.5 mm. By plug connections with precisely defined positions of the light guides, the light guide probe is connected to an illuminating device having a xenon lamp and to a diode line spectrometer. The diode line spectrometer has an aperture ratio which includes the aperture of the light guide without trimming or vignetting.
