More information on vacuum compatible PI products»
Many aerospace and astronomy-related applications require motion components that work reliably in low temperature and/or high vacuum conditions. PI can offer a variety of positioning stages, actuators and piezo components that can work under these conditions. PI has provided precision motion components for space based applications and for the Mars Mission.
