Piezo Scanners for Microscope Lenses (Nanofocus Z-Scanner)

These piezo lens positioners and scanners Z-nanopositioning mechanisms are often used to move microscope objectives with extreme resolution and speed, typically one order of magnitude higher than conventional motor driven positioners. Their controllers are compatible with major image acquisition software packages, to provide high performance images for deconvolution microscopy, Z-stack image acquisition and other super-resolution techniques. Settling times are typically in the low millisecond range. High guiding precision is achieved with frictionless, computer optimized flexures. Capacitive sensors guarantee sub-nanometer precision in closed-loop operation.

Travel ranges up to several 100µm are feasible with piezo stack/flexure drives. A 2mm version with PiezoWalk® motor drive is available as the N-725.  For longer travel ranges, electromagnetic drives are also available.

How Piezo Actuators and Flexures Work

With the use of flexures mechanisms, the motion of a piezo stack can be multiplied many times to achieve up to one millimeter travel (or more in extreme cases).  Flexures can be designed to also double as guiding and preloading mechanisms. Flexure motion is based on the elastic deformation (flexing) of a solid material. Friction and stiction are entirely eliminated, and flexures exhibit high stiffness, load capacity, and resistance to shock and vibration. Flexures are maintenance free and not subject to wear. They are vacuum compatible, operate over a wide temperature range, and require neither lubricants nor compressed air for operation.
