Open-loop Z-stage for phase control in optical interferometers
In precision optical systems and interferometer applications, the control of minute optical phase shifts significantly impacts measurement accuracy and analysis results. Even slight displacement differences can affect the stability of interference fringes and measurement outcomes. The S-312 optical phase shifter is an open-loop piezo Z-stage designed for interferometers and precision optical applications. Its flexure guide structure enables smooth operation without backlash, supporting stable phase adjustments through fine displacement control. Its compact design makes it suitable for integration into optical benches and devices. 【Application Scenarios】 - Interferometer experiments - Optical phase shift control - Holography/wavefront control experiments - Precision optical alignment 【Benefits of Implementation】 - Stable phase adjustments through fine displacement control - Highly reproducible optical measurements - Improved device integration capability
