The units can be clamped at the flanges. The S-224 is specifically designed for open-loop operation. The S-226 closed-loop version is available for highest accuracy and repeatability. The S-224 and S-226 are delivered with a Æ 15 x 4 mm BK7 glass mirror. Open- and Closed-Loop Operation In open-loop operation, the platform's angular position is roughly proportional to the drive voltage (see link in the "Tutorial" section for behavior of open-loop piezos). The open-loop models are ideal for applications where the position is controlled by data provided by an external optical sensor, a CCD camera, etc. The closed-loop version (S-226) allows absolute position control, high linearity, and repeatability based on the internal ultra-high-resolution feedback sensor. Working Principle S-224/S-226 miniature tilt platforms are equipped with low-voltage piezoelectric linear drives (0 to 100 V) pushing a frictionless, flexure-mounted platform. The flexure is FEA (finite element analysis) modeled for zero stiction, zero friction and exceptional guiding precision; it also serves as the pivot point and preload for the PZT.
