Contact SupplierThe p72 series offer a nano positioning and scanning range up to 110î¼m(max). And it offers a compact size, and an outstanding resonant frequency. The system is well suited for high precision positioning applications with nanometer resolution. The successful parallelogram design guarantees high parallel motion without influencing the optjical path. The positioning repeatability can be guaranteed by an integrated measurement system. The design with integrated pre-load of the actuator offers the following advantages: high resonant frequency and highly parallel motion. Adapter thread rings for the nose piece are available separately. They allow for fast mounting and exchanging of the system on the microscope. Other objectives no longer need to be removed.
P72 piezoelectric objective scanner is a Z-axis motion piezo positioner specially designed for objective lens focusing microscopy. It adopts a frictionless flexible hinge parallel guiding mechanism, with ultra-high focusing stability. The objective positioner is loaded with a microscopic detection/measurement or observation device to improve accuracy.
