PZTOL Piezoelectric Objective Displacer

Product Description

• Open-loop controlled piezoelectric objective displacer for Z-axis positioning travel
• Enables rapid acquisition and high frame rate scanning
• Quick-release flexure clamp ring for fast objective lens replacement
• Suitable for scenarios requiring high repeatability and fine relative motion instead of absolute positioning
• Must be used with the OPZT-1U single-channel piezoelectric controller (purchased separately)
• Objective lens adapter of the OL series is required for objective lens installation (purchased separately)

The piezoelectric objective displacer system is a high-speed, high-precision Z-axis focusing solution specially designed for the field of microscopic imaging.

Technical Notes

1. The piezoelectric objective displacer system is a high-speed, high-precision Z-axis focusing solution exclusively designed for microscopic imaging. Adopting piezoelectric ceramic drive technology, the system achieves fast, high-repeatability scanning with a 60μm Z-axis travel, and is particularly suitable for microscopic applications requiring high-speed focusing, 3D imaging and high frame rate acquisition. It must be used with the OPZT-1U single-channel piezoelectric controller (purchased separately).Application Scenarios

The OPZT-1U is a single-channel piezoelectric controller specially designed for piezoelectric ceramic actuators (including piezoelectric objective displacers, piezoelectric extenders, piezoelectric stages, etc.). Integrating intelligent identification, precision regulation and multiple control modes, the controller provides users with an intuitive and convenient operating experience through a 1.54-inch OLED Chinese menu interface.

The objective lens holder is equipped with M4 threaded holes, compatible with connecting rods for use in free space. Select the corresponding model according to the objective lens thread; the dovetail quick-change design supports a variety of threads such as RMS, SM1, M25, M26 and M32.
