2-Axis System (Vacuum) Example Systems - ZMI™ Series

ZYGO has a full line of vacuum compatible interferometers and feedthroughs for applications ranging from 2-axis systems to complex multi-axis vacuum applications. This example ZMI™ system uses the 7702 laser, a 2402 2-axis VME measurement board, and vacuum-compatible, compact interferometers.

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.
