SPECTROMETER

摘要

A spectrometer comprising a carrier, a light input for measurement for light disposed on the carrier, a diffraction grating disposed on the carrier for dispersing the measurement light, an opto-electronic detector disposed on the carrier for receiving and detecting the measurement light following dispersion by the grating and at least one optical component for imaging the measurement light on the diffraction grating is characterized by a base board for supporting the opto-electronic detector, the base board being so fastened to the carrier so as to allow a thermal expansion which substantially compensates the drift of the spectrolight component relative t o the detector.
