Miniaturization – Finger-Tip Sized Positioners, Inertia Piezo Motors
The need for miniaturization of instruments requires opto-mechanical alignment, positioning, and assembly on a smaller scale. Direct drive piezo inertia motors that are only a few millimeters in size enable ultra-compact nano-positioning stages, as small as a finger-tip. PI provides standard and custom designs for OEMs including linear, rotary, XY, XYZ and 6 degree of freedom systems.
High-Speed Parallel Photonics Alignment Engines for SiP Test and Automation
PI’s photonics alignment product line addresses the requirement of aligning multiple parallel optical paths with multiple, interacting inputs and outputs, all requiring optimization. The automated alignment engines include 3 to 6-axis mechanisms, controllers with firmware based alignment algorithms, and the software tools to meet the high accuracy demands of different markets, such as packing, planar testing, or inspection. Hexapod 6-axis parallel positioning systems are instrumental to fast SiP alignment due to their lower inertia, improved dynamics, smaller package size and higher stiffness, and programmable pivot point.
Precision Motion and Automation: Engineered Systems, Linear Motors / Air Bearings / Piezo Flexures
PI develops complete engineered motion systems for precision automation applications including laser machining and flat panel inspection. Air bearings with linear motor drives provide vibration-free motion, highly constant velocity control, along with best in class accuracy and geometric performance. When short travel ranges are concerned, piezo flexure-guided linear positioners offer excellent precision and responsiveness with step and settle typically in the millisecond range and billions of cycles of service life.
Microscopy Imaging and Bio-Nanotechnology Solution Packages
Researchers require the sub-atomic resolution and extreme responsiveness of piezo nanopositioners to create higher-quality images faster. PI provides a large variety of fast XY (Z) stages and piezo collar lens positioners for 3D imaging (Z-stack acquisition), deconvolution, and fast auto-focusing applications. A line of ultra-stable long-travel microscope stages with self-locking piezo motors is also available.
