Voice Coil & Piezo Collar Objective Scanners |
PI provides a large variety of piezo and voice coil motor driven nanopositioning stages for focus control and fast objective lens positioners (Z-motors, piezo collars), and piezo z-stages (slide-scanners, sample scanners) for deconvolution and 3D imaging (Z-stack acquisition) and fast focusing applications.
Why Choose PI Z-Scanners w/ Voice Coil and Piezo Motors?
PI's piezo-actuated Z-scanners typically achieve 10 times higher focusing speed & precision than classical motorized drives. Our new V-308 Voice Coil vertical slide combines longer travel and nanometer resolution.
Compatible with All Major Image Acquisition Packages
PIFOC® controllers come with a high-bandwidth analog interface for extremely fast response and compatibility with all major image acquisition packages. |
New Lower Cost Fast Piezo Focus Packages with Digital Control & Software
For the most commonly used travel ranges and objective diameters, PI has now put together lower cost PIFOC® packages with a new compact digital controller and software. Datasheet: PIFOC® Fast Piezo Focus Systems
These systems also integrate seamlessly with the
Focus Trac™ Laser Autofocus systems.
