Abstract
A spectrometer is provided having a carrier, a light input for measurement light disposed on the carrier, a diffraction grating disposed on the carrier for dispersing the measurement light received from the light input, an opto-electronic detector disposed on the carrier for receiving and detecting the measurement light dispersed by the diffraction grating, at least one optical component for imaging the measurement light on the detector through the diffraction grating, a base board fastened to said carrier for supporting the opto-electronic detector, wherein the opto-electronic detector is fastened at a predetermined position on the base board, and wherein the base board and the carrier include positioning members for relatively positioning the base board on the carrier in a predetermined position. Preferably, the detector is a detector chip excluding a housing and fastened in a predetermined position on the base board. Both, carrier and base board have cooperating positioning members for positioning the base board on the carrier. The base board is preferably an electronic circuit board being fastened to the carrier in such a manner so as to allow a thermal expansion, and wherein t…
