Abstract:
1. A photon density wave spectrometer, comprising: a measuring chamber loaded with a sample to be measured; and a coupling-in/coupling-out device configured for receiving excitation light from a light source and for coupling-in on the sample to be measured in the measuring chamber and for receiving measurement light formed in the sample to be measured on account of the coupled-in excitation light and for feeding the measurement light to a detection device; wherein the coupling-in/coupling-out device has an optical switching device and a plurality of optical waveguide elements coupling thereto with a respective optical waveguide connected by the optical switching device according to at least one selectable measurement configuration, to couple-in the excitation light corresponding to at least one selectable measurement configuration and to receive the measurement light, so that depending on a connection of an individual optical waveguide element, the excitation light and the measurement light is guided by an associated optical waveguide; wherein outputs of the several optical waveguide elements are positioned in a viewing direction towards outputs corresponding to a spiral-shaped arrangement.
