Measurement Electronics
ZMI™ Series – Displacement Measuring Interferometers
ZMI™ measurement electronics calculate displacement using optical signals from the interferometers driven by a ZMI™ laser source.
The ZMI™ 501A provides two axes of measurement in a convenient stand-alone enclosure.
The ZMI™ 2400, 4000, and 4100 series boards provide sub-nanometer resolution to service the most challenging position metrology applications. These boards can be modularly added in a VME chassis to provide scalability up to 64 axes of measurements.
For ultimate measurement precision, our patented Cyclic Error Correction option automatically and seamlessly eliminates common non-linear errors intrinsic in DMI systems.
