In the course of the last four decades, PI has become the leading manufacturer of nanopositioning technology.
In the 70s, as space exploration stimulated optics research, PI introduced piezo actuators which gave scientists the highest positioning precision then available.
In the 80s, as the development of the microcomputer led to the first semi-conductor boom and ongoing miniaturization of electronic structures, PI introduced nanopositioning systems tailor-made for the tasks involved.
The fall of the Berlin Wall marked the end of the Cold War and made the 90s the opening of a new era of boundless communications. For PI also, this meant the opening of new horizons with the founding of the PI Ceramic subsidiary in the former East Germany.

The turn of the century brought global progress in photonics, nano- and biotechnology—all fields where "smaller" and "more precise" are keys to success.

PI also offers the appropriate solutions for tasks in these areas with ever faster and more precise nanometer positioning, stabilization and automation.
