P73 is large-stroke piezo objective scanner. The linear movement range of Z axis could be selected from 200μm, 500μm, and 1mm. It adopts flexible hinge design mechanism, which has no friction, good linearity of motion, and high positioning accuracy of closed-loop models. Separate screw adapter design, can be adapted to a variety of microscopes, widely used in large-scale microscopic imaging, two-photon microscope and other fields.
Features
• Optional travels: 200μm/500μm/1mm
• Capacity: 0.4kg
• Millisecond response time
• Closed loop for higher repeatabilit
• Excellent focus stability

Thread Adapter for Easy Integration
P73 series objective positioner is connected to the objective lens through an adapter to quickly make the objective lens in the desired position. A variety of thread adapters are available, such as M27×0.75, M26×0.75, M26×1/36”, M25×0.75, W0.8×1/36”, etc., which can also be customized for easy integration with the microscope.
