PURPOSE:To reduce the number of detectors, and to lower the cost of a photometer, by forming the pitch of two sets of optical fibers differently from that of cells so that the measuring light from the optical fibers on one side of the sets of optical fibers each consisting of two optical fibers transmits the cells, and the measuring light of the set on the other side abuts with the upper plane of the table between the cells. CONSTITUTION:The optical fibers 15a-15d are constituted of the sets of optical fibers, each set being composed of two optical fibers, and the pitch of the optical fibers 15a-15d is formed differently from that of the cells so that the measuring light from the optical fibers 15a and 15c on one side transmits two cells 12 respectively at time of photometry, and the measuring light from the optical fibers 15b and 15d on the other side abuts with the turntable 11 between cells. Therefore, when the measuring light lambda1 and lambda3 having different wavelengths from the optical fibers 15a and 15c transmit two cells 14 respectively, the measuring light lambda2 and lambda4 having different wavelengths from the optical fibers 15b and 15d on the other side are abuts with the turntable 11, and do not transmit cells 14. Thus, since no simultaneous detection of the measuring light lambda1, lambda2 and lambda3, lambda4 can occur, it is possible to detect the four kinds of measuring light only by two detectors 16a and 16b. |
