Long-term stabilization of microscope focus with inertial drive and position feedback.
In microscopic observation, maintaining high precision focus on the observation target is essential. Especially under conditions of long-term observation or environmental fluctuations, focus drift can affect the quality of observation. The N-472 series is a piezo micro-positioning actuator equipped with position feedback from an incremental encoder. It achieves high-resolution positioning through an inertial drive (stick-slip) method, ensuring stable maintenance of the microscope's focus position over extended periods. Furthermore, when stopped, it retains its position through a self-locking mechanism, eliminating the need for current and reducing heat generation. This enables stable focus control even in long-term observation environments. 【Application Scenes】 - Microscope focus adjustment - Cell observation - Semiconductor inspection 【Benefits of Implementation】 - Improved observation accuracy through high-precision focus control - Enhanced observation efficiency due to long-term stability - Energy-saving design that does not require current except during operation
