PURPOSE:To simplify structure by adjusting the optical axis of a photodetection part corresponding to a shift of a light beam from a sample and aligning it to the light beam. CONSTITUTION:A two-dimensional light position detector 4 is arranged in the optical measurement system consisting of a light source part 1, sample holder 2, and photodetection part 3 along the optical path from the holder 2 to the photodetection part 3, and a movement adjusting device 5 is combined with the photodetection part 3. Then, the deviation of the holder 2 from prescribed inclination due to strain caused by heat contacting is detected by a detector 4 and the photodetection part 3 is moved by the adjusting device 5 so that its optical axis is aligned to the light beam. Consequently, it is not necessary to fit an adjusting device to the holder 2. |
