There is disclosed a specimen measurement apparatus including means for sequentially moving individual specimens, radiation means for simultaneously radiating first and second radiation beams on first and second positions spaced apart from each other in a moving direction of the specimens, light detection means for time-serially detecting light components emerging from specimens passing the first and second positions using the same light detector, and optical selection means, arranged in an optical path between the radiation positions and the light detection means, for, when a specimen passes the first position, selectively guiding a light component having a first optical characteristic emerging from the specimen to the light detection means, and for, when the specimen passes the second position, selectively guiding a light component having a second optical characteristic emerging from the specimen to the light detection means. |
