Researchers grappling with microscopic drift during long-duration imaging experiments now have a powerful solution. The newly introduced U-781 inverted microscope XY stage system combines cost-effectiveness with cutting-edge technology to deliver unprecedented stability for super-resolution fluorescence microscopy.

At the heart of the U-781 system lies an advanced ultrasonic piezoelectric motor drive technology that achieves remarkable 10-nanometer resolution while operating across an exceptionally wide speed range—from 100 nanometers per second to 120 millimeters per second. This dynamic performance is complemented by rapid stabilization times measured in milliseconds, making the platform ideal for applications requiring both fast positioning and precise tracking.

The compact, low-profile design incorporates integrated piezoelectric ceramic actuators that minimize vibration and heat generation—critical factors for maintaining stability during extended observation periods. With a generous 128×86 mm travel range, the system accommodates diverse sample configurations while maintaining compatibility with inverted microscopes from major manufacturers including Nikon, Leica, Olympus, and Zeiss.

The piezoelectric motor technology offers distinct advantages over traditional stepper motor systems. Its dual-frequency drive mode enables smooth, shock-free motion with reduced operational noise, while an adaptive parameter mode intelligently adjusts settings based on movement patterns to optimize performance.

The system's self-locking piezoelectric ceramic design eliminates servo jitter and drift common in electromagnetic systems, providing exceptional rigidity. This innovation enables stable operation across six orders of magnitude in speed variation. When paired with high-performance motion controllers, the advanced digital servo system ensures rapid, precise positioning through automatic PID parameter adjustment.

The U-781 platform ships with extensive software support, including interfaces for popular microscopy and analysis packages such as:

• µ-Manager
• Nikon NIS Elements
• MatLab
• LabView
• Python
• PI MikroMove

The system includes a high-performance dual-axis motion controller and ergonomic joystick, with support for both Windows and Linux operating systems.

The platform's modular design accommodates various sample holders including standard slides, multi-well plates, and petri dishes. For researchers requiring three-dimensional precision, the system integrates seamlessly with PI's Z-axis nanopositioning devices such as the P-736 PInano Z or P-545 XYZ piezoelectric nano-positioning stages.

When combined with the P-545 PInano XYZ platform—which offers sub-nanometer closed-loop resolution—the system becomes particularly valuable for super-resolution microscopy applications including single-molecule tracking and optical tweezers experiments.
