Z-Stack Imaging & Auto-Focusing: Faster with Piezo Focus Motor Drive Nanopositioners and Voice Coil Motors
PIFOC focus drive motors and nanopositioners for microscopy and metrology are piezo-motor and voice coil-motor actuated Z-scanners that achieve typically 10 times higher focusing speed & precision than stepper motor stages and thus provide higher-quality images faster. They are used in high performance metrology, auto-focusing and scanning applicatoins.

Moving / Scanning the Objective
The compact, light and stiff lens / objective scanner design provides very fast response and does not disturb the sample.

About PI
PI, the global leader in nanopositioning, has been ISO 9001 certified since 1994. PIs patented piezo technology provides longer lifetime and higher performance than any other piezo device on the market. PIFOC technology was invented by PI in the 1990's and has since become the global standard in fast objective motor scanners, with thousands of units installed in the field.
