Each straight guide consists of two struts and one leaf spring parallelogram (figure 1). The struts are fabricated in pairs of two to ensure strut parallelism and equal length. The parallelogram leaf springs are connected by a lightweight ceramic boxshaped bridge.
Finite element analysis of the assembled system predicts the first resonance frequency to be at 1.4 kHz (figure 2).
