Long-term stable optical fine-tuning with inertial drive and position feedback.
In optical systems, high-precision optical axis adjustment and positioning are crucial. The position of optical elements such as lenses and mirrors significantly affects system performance and measurement accuracy. Even slight positional deviations can lead to a decrease in image quality and an increase in measurement errors. The N-472 series is a piezo micro-positioning actuator equipped with position feedback from an incremental encoder. Its inertial drive (stick-slip) method achieves high-resolution positioning and long-term stability, enabling precise alignment adjustments of optical elements. Additionally, the self-locking mechanism holds the position when stopped, eliminating the need for current and reducing heat generation. This ensures stable optical adjustments over extended periods. [Application Scenarios] - Adjustment of objective lenses in optical microscopes - Optical axis adjustment in laser processing machines - Positioning in semiconductor manufacturing equipment [Benefits of Implementation] - Improved system performance through high-precision positioning - Reduced maintenance frequency due to long-term stability - Position feedback enabled by the built-in incremental encoder
