Miniature Linear Encoder features 1.2 nm resolution.

Press Release Summary:

Employing miniature sensors, Mercury II(TM) encoders offer linear resolutions from 5 µm to 1.2 nm and rotary resolutions up to 268M cpr to upgrade motion systems. Short- and long-range accuracies are respectively rated up to ±20 nm and ±1 µm, and vacuum models are rated up to 10-8 torr. Options include scales with cut-to-length PurePrecision(TM) laser tape, featuring stick-on index and limits; linear glass, featuring stick-on index and limits; and rotary versions.

World's Smallest Linear Encoder Features 1.2nm Resolution

Bedford, MA - MicroE Systems' Miniature Encoders are Ideal for XY Microscope Stages, Sub-Micron and Nanometer Positioning Systems, Piezo-Motor Stages and Fine Control of Optics

See how MicroE Systems' newest Mercury II(TM) encoders, with miniature sensors and resolutions up to 1.2nm, can upgrade your motion system!

Specifications Include:
  • Linear resolutions from 5µm to 1.2nm
  • Rotary resolutions up to 268M CPR
  • Short-Range Accuracy up to ±20nm
  • Long-Range Accuracy up to ±1µm
  • Vacuum models up to 10-8 torr

  • Cut-to-length PurePrecision(TM) laser tape with stick-on index and limits
  • Linear glass with stick-on index and limits; low expansion glass available
  • Rotary scales

    Key Features:
  • Tiny sensors
  • Wide setup tolerances
  • User-programmable resolution
  • Robust tolerance to scale contamination
  • Lowest power consumption
  • Software for encoder setup and data plots

    Mercury II encoders enable compact system designs with a sensor as short as 8.7mm and tape scale only 6mm wide. Models include programmable interpolation up to x16384 - right in the sensor. Users benefit from digital or analog output from the sensor, especially a smaller footprint and a variety of connector options - including customer-specific connectors.

    The small size, excellent operating performance, integrated interpolation electronics, low power consumption and ease of installation make Mercury II encoders perfect for a wide range of precision motion control and metrology applications. High speed applications are supported by new, faster A-quad-B output and serial word versions - up to 10m/s with 1.2nm resolution!

    In addition to Mercury II encoders, MicroE Systems makes small-diameter rotary, low-cost PCB mount and vacuum-rated models, all RoHS compliant.
