(a) Photograph of the single-beam optical-trap sample holder and X-ray diffractometer. The red and green arrows indicate the synchrotron radiation beam and the OPS laser beam used for the single-beam optical trap, respectively. The orange arrow indicates the semiconductor laser beam for illuminating the sample particle. (b) and (c) Photographs of the sample cell used for the optical trap. In (b), a non-spherical lens is attached to the side face of the sample cell. |
