A miniaturized detector cell (4) having a measuring chamber volume of 25 fl-1 mu l is described. In spite of its miniaturized construction, the detector cell has an optical path length of about 0.1-100 mm. The incident measuring light (R) is repeatedly reflected at the inner walls (23, 25, 26) of the interaction region (21 ) before it leaves the detector cell (4) again. In a preferred manner, the detector cell (4) is manufactured from silicon or quartz by photolithographic means.
