When testing, the auxiliary platform can be placed in the chamber of the measuring instrument, the test piece to be tested is placed in the sample groove 13, and the light path of the light path hole 21 is debugged and aligned. For example, the turntable 1 can be adjusted to a required large angle, redundant light is shielded by the light shielding plate 2, the light is enabled to fall at the right center of the position of the test piece to be tested by adjusting the light shielding plate 2, and the test work can be performed after the alignment and the light path are adjusted in place. When the measuring instrument does not have a self-contained laser alignment light path, the laser pen can be placed at the right center of the light path hole 21, and the laser pen is excited to perform light path alignment.
