Be it in science or product development: Being ahead means relying on the components used. PI is used for differentiation purposes, because drive components, positioners or systems by PI can make all the difference in "state-of-the-art technology".
Many scientific publications cite PI systems, as they are an important requisite for successful research and development projects. Bespoke developments for public research are a daily business for PI. Extreme ambient conditions and new designs are just as common as are slight modifications for better adaptation to applications. Important fields of research are, for example, beamline instrumentation, micro systems, and nanotechnology.
And often enough, developments at universities, with PI supplying the main components, form the basis for establishing own successful and innovative companies.
