The OMEGA Laser Facility is used for laser driven inertial confinement fusion research at the University of Rochester's Laboratory for Laser Energetics. This facility requires 1 millimeter diameter spherical targets placed at the center of an experimental chamber to remain stable to within 5 microns (0.0002"). Occasionally a mounted target will exceed this stability specification due to ambient vibration, so an isolation stage is proposed as a means of eliminating this problem. This isolation stage consists of six parallel flexures that are axially loaded to reduce the resonant frequency of the isolator. Frequency versus axial load, damping, and linearity are measured and compared to results in the literature. Difficulties in achieving the required performance are discussed, and a simplified isolator geometry is proposed.
