In the field of precision microscopic imaging and micro-nano detection, the accuracy, speed and travel of Z-axis focusing directly determine the imaging quality and operational efficiency. P79.Z500 piezo nano positioning stage is a technical continuation and scenario expansion of our classic series. With a core advantage of a 500μm large stroke, a central large hole, and millisecond-level rapid response, it precisely targets the demand for large-stroke precise focusing and meets the precise micro-movement requirements of different scenarios.

The P79.Z500 piezo nano positioning stage is a nano positioning stage specially designed for Z-axis precision micro-motion. With a larger stroke, high precision, fast response and strong adaptability, it continues the core advantages of the P79 series and provides a more comprehensive solution for various precision micro-motion scenarios.

The core upgrade point of the new P79.Z500 piezo nano positioning stage is that the maximum stroke can be up to 500μm. Compared with the original 100μm and 200μm strokes of this series, it has achieved a significant expansion of the stroke. It can not only meet the requirements of fine focusing but also adapt to the needs of a wide range of Z-axis travel, making precise focusing more flexible.

Inheriting the classic central through-hole structure of the P79 series, this design takes into account the different fixation requirements of samples in actual operations. It can be perfectly compatible with various sample holding mechanisms and loading accessories on the market. Whether it is conventional slides, petri dishes, or special tooling fixtures, it can be easily adapted, and installation and debugging are more convenient.

Based on piezoelectric ceramic drive technology, the response time of P79.Z500 can be short to millisecond level, with no friction and no backlash, and the focusing process is fast and smooth. It can not only accelerate the focusing speed and improve the efficiency of microscopic imaging capture, but also adapt to the high-frequency operation requirements of automated production lines, effectively enhancing the overall production inspection efficiency.

P79.Z500 ensures a large stroke while still maintaining nanometer-level positioning accuracy. The flexible hinge structure design provides high-stiffness support, ensuring no drift or vibration during operation. Even when carrying samples or fixtures of a certain weight, it can guarantee the stability and repeatability of each focusing and displacement.

II. P79.Z500 Piezo Nano Positioning Stage Has a Wide Range of Application Scenarios

Core Application: Focusing of Samples in Microscopic Systems

    The core application scenario of P79.Z500 is the precise Z-axis focusing of samples in microscopic imaging systems, and it is also a dedicated micro-motion accessory designed to be compatible with the macro motion XY-axis microscopic scanner and piezo motor. In actual operation, after the macro XY-axis motion stage completes the planar positioning of the sample, P79.Z500 can then proceed with the subsequent Z-axis focusing work: driving the sample to rise and fall along the optical axis at the nanometer level in a straight line. Combined with closed-loop feedback control, it can quickly achieve sample focusing and complete clear imaging. The macro and micro combined positioning method not only ensures the imaging range but also guarantees the focusing accuracy. It is an ideal choice for applications such as biological activity detection, live cell imaging, and tissue section scanning, and is perfectly compatible with various optical microscopes, super-resolution microscopes, and biological microscopes.

Compared with conventional focusing mechanisms, P79.Z500's millisecond response can significantly reduce focusing time. Its 500μm large stroke can meet the focusing requirements of different samples and layer-by-layer scanning. The central through hole is suitable for holding various samples, making it particularly suitable for scenarios with high requirements for focusing accuracy, stroke, and speed, such as biological cell observation, material microscopic analysis, and chip surface inspection.
