Single-Moving-Platform, Parallel-Kinematics Design: EqualDynamics for all Axes, Better Linearity & Temperature Stability Open / Closed-Loop Operation In open-loop operation, theplatform angle roughly corre- sponds to the drive voltage (see page 4-17in the “Tutorial” section for behavior of open- loop piezos). The open-loop models are ideal for applica-tions where the position is con- trolled by an external loop, based on data provided by a sensor (e.g. PSD, quad cell,CCD chip, etc.). The closed-loop versions areequipped with two pairs (one per axis) of LVDT (linear vari- able differential transformer) sensors operated in a bridge circuit for ultra-high resolutionand angular stability. They pro-vide sub-µrad resolution and repeatability. for our comprehensive line oflow-noise modular and OEMcontrol electronics for comput- er and manual control. S-340 piezo tip/tilt platformsare fast and compact tilt units, providing precise angular movements of the top platform in two orthogonal axes. The tip/tilt range is 2 mrad (equiva-lent to 4 mrad optical beamdeflection) with sub-µrad reso-lution. Closed-loop versionsare available for highest accu- racy and repeatability. S-340 systems are designed for mir-rors up to 100 mm diameterand have outstanding angular stability over a wide tempera- ture range.To match the CTEs (coefficientsof thermal expansion) of vari-ous mirror materials, platformsmade from different materials are available (see ordering information). Notes See the “Selection Guide” on p. 3-8for comparison with other steering mirrors.See the “Piezo Drivers & Nano-positioning Controllers” section

piezo drives operating as a unit in push/pull mode. The alu- minum case is equipped withan integrated, FEA-modeled(finite element analysis) circu- lar flexure featuring zero stic- tion, zero friction and excep- tional guiding precision. Since drives and guides are frictionless and not subject towear and tear, these units offeran exceptionally high level of reliability. Materials Match
