The stability of beamline optics directly affects the beamline’s performances, such as coherence, focal size, position stability of the beam and so on, it has become a serious issue for a low emittance 4th generation light source. The vibration transmitting function of supports plays a big role in the stability performance of the optics. In order to find out a stable supporting structure, several types of support structures were tested, and the transfer ratio were described. The result shows that wedge struc-tures generally have a lower transfer ratio, and point contact support structures should be avoided.
