| | | Open / Closed-Loop Operation In open-loop operation, the platform angle roughly corresponds to the drive voltage (see page 4-17 in the "Tutorial" section for behavior of open-loop piezos). The open-loop model is ideal for applications where the position is controlled by an external loop, based on data provided by a sensor (e.g. PSD, quad cell, CCD chip, etc.). The closed-loop version is equipped with two pairs (one per axis) of strain gauge sensors operated in a bridge circuit for ultra-high resolution and angular stability. They provide sub-urad resolution and repeatability. Higher Performance Through Parallel Kinematics S-330 tip/tilt platforms feature a single moving platform, parallel-kinematics design with a | | |

| | | S-330 piezo tip/tilt platforms are fast and compact tilt units, | | providing precise angular movements of the top platform in two orthogonal axes. The tip/tilt range is 2 mrad (equivalent to 4 mrad optical beam deflection) with sub-urad resolution. Closed-loop versions are available for highest accuracy and repeatability. S-330 systems are designed for mirrors up to 50 mm diameter and have outstanding angular stability over a wide temperature range. To match the CTE (coefficient of thermal expansion) of Zerodur glass, the S-330 is equipped with an invar top platform. | | |
