2-Axis System (Vacuum), ZMI™ Series

Light from the 7702 laser travels through a vacuum window into the vacuum system, where it is distributed with beam splitters and fold mirrors. The modular design of ZMI™ components allows great flexibility for positioning the interferometers inside the vacuum system. Measurement signals are collected by the fiber optic pickups in the vacuum system and transmitted through a vacuum feedthrough to the 2402 measurement board.
