The Keysight E1720A provides ultra-high resolution (0.6 nm) measurements and servo-controlled positioning for use in dimensional metrology and motion control. It is a compact, integrated solution for precisely-controlled linear positioning used in precision stages and other precision machinery, and also in writing servotracks in the data storage industry.
The standard E1720A system consists of a Keysight E1711A Sensor Head, an E1713A Scale Servo-Axis Board, an E1712A opt 011 Linear Scale, and a connecting cable. The Keysight E1723A DSP Servo-Axis Board can be substituted for the E1713A by ordering option 023. Different scale lengths and configurations are also available.
Repeatability of 2nm
Short range accuracy of 10 nm
Rugged construction for long-term, reliable performance
Immune to turbulence created by stage motion and changing conditions.
