S-224, S-226 qX Ultra-Fast Miniature Piezo Tilt Platform with Mirror
S-224/S-226 Miniature Tilt Platforms are extremely fast and compact tilt units, providing a tilt range of 2.2 mrad and sub-millisecond response. 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. S-224 and S-226 are delivered with a Æ 15 x 4 mm BK7 glass mirror providing a flatness of l/8 and reflectivity > 92 % at 633 nm.

- 2.2 mrad Tilt Range
- Optional Position Feedback Sensor
- Includes BK7 Mirror
In open loop operation, the platform’s angular position roughly corresponds to the drive voltage (see "Tutorial: Piezoelectrics in Positioning" 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.
Application examples:
Laser beam steering & scanning, correction of polygon scanner errors, laser beam stabilization.Working principle:
S-224/S-226 Miniature Tilt Platforms are equipped with low voltage piezoelectric linear drives (0 to 100 V) pushing a flexure mounted platform. The flexure is FEA (Finite Element Analysis) modeled for zero stiction/friction and exceptional guiding precision and serves as the pivot point and preload of the Piezo.Steering Mirrors Selection Guide
