Patent ID: 8868156

Claim:
A device for use in optical spectroscopy, comprising: at least one light source; and at least one spectrometer, wherein the at least one light source and the at least one spectrometer are fabricated integratively, the optical components of the at least one spectrometer being optical microcomponents which are mounted integratively on at least one of a top side and a bottom side of a substrate board, wherein the at least one spectrometer includes: a focusing lens mounted on the bottom side of the substrate board for focusing a first light beam radiated by the light source onto at least one reaction vessel-underneath the substrate board; a collective lens mounted on the bottom side of the substrate board for converging a second light beam emanating from the reaction vessel onto a dispersive element mounted on the top side of the substrate board; and at least one detector assigned to the dispersive element; the substrate board having a light-transmitting region above the focusing lens and the collective lens, wherein the optical microcomponents are mounted monolithically on the substrate board.
