PI (Physik Instrumente) is a privately owned global leader in precision motion control, nanopositioning, and automation technologies for photonics and optical applications. For more than 50 years, PI has designed and manufactured world-class motion solutions, including nanopositioning stages, air-bearing systems, hexapods, fast steering mirrors, piezo actuators, and automated photonics alignment platforms. With engineering and manufacturing facilities across North America, Europe, and Asia, PI employs more than 1,900 people in 15 countries and serves leading companies, research institutions, and OEMs worldwide.
PI technologies enable critical optical processes across industries including telecommunications, semiconductor manufacturing, aerospace, metrology, quantum technologies, and scientific research. The company's precision motion systems provide the stability, accuracy, and dynamic performance required for optical testing, inspection, alignment, and manufacturing applications where nanometer-level positioning directly affects performance and yield.
PI's air-bearing motion systems are widely used in optical metrology, semiconductor inspection, and precision measurement applications. Their frictionless, wear-free operation delivers outstanding straightness, smoothness, and repeatability, making them ideal for high-accuracy scanning, interferometry, optical surface characterization, and advanced inspection systems.
The company is also a leader in fast steering mirror (FSM) technology, providing high-bandwidth beam steering and stabilization solutions for demanding photonic applications. PI fast steering mirrors are utilized in free-space optical communications, including laser communication links between satellites, where precise beam pointing and stabilization are essential for maintaining reliable, high-data-rate connections. Fast steering mirrors are also employed in laser machining and materials processing systems to enable high-speed beam positioning, process optimization, and enhanced manufacturing throughput.
For photonic integrated circuits (PICs), silicon photonics (SiPh), co-packaged optics, and advanced fiber-optic devices, PI offers industry-leading automated photonics alignment systems. These high-speed, multi-axis alignment platforms combine precision motion hardware with advanced alignment algorithms to optimize optical coupling efficiency during research, prototyping, and high-volume production.
PI's photonics alignment solutions help manufacturers improve yield, reduce assembly time, and accelerate the commercialization of next-generation optical communication and sensing technologies.
With extensive in-house engineering expertise and a broad portfolio of proven motion technologies, PI can rapidly adapt existing solutions or develop fully customized systems tailored to specific optical requirements. From piezo actuators and nanopositioners to complete multi-axis alignment and automation platforms, PI delivers the precision, reliability, and application knowledge required to help customers advance optical innovation and maintain a competitive advantage in rapidly evolving photonics markets.
