High-Accuracy Contour Detector Using Laser Optical Diffraction Scale 0.025 μm Resolution.




New High-Accuracy Contour Detector that Weighs 40% Less Than Previous Models

  • Laser optical diffraction scale ensures high resolution over the entire range.
  • Contours can be measured and analyzed with high accuracy and high resolution.


Optical Diffraction Scale

The laser wavelength of the light source is highly stable, and is not affected by air fluctuation or pressure change. This scale has high repeatability and no backlash errors occur.


Linear Motor Drive

  • Low vibration, high accuracy, high-speed movement.
  • Low vibration ensures more stable measurement at high magnifications.


A Choice of Linear Series DX Type or SD Type to Suit Specific Needs

Available as an all-in-one space-saving DX Type or conventional separate style SD Type.


Outstanding Expandability

  • Roughness detector and CNC table can be added.
  • Flexible design ready to meet future requirements.









Flexible Arm and Probe Combination

  • This model uses a master ball calibration to correct the arc distortion (X-direction error) characteristic of a contour detector and has the ability to combine a flexible arm and a probe.
  • Various contour measuring styli for a wide variety of workpieces from small holes to deep grooves.

In the case of a long workpiece like a ball screw, measuring with a conventional arm and probe position relationship resulted in interference with the detector, making it impossible to achieve a large measuring range in the X-direction. Master ball calibration creates a combination in which the arm and probe are downwardly offset, as shown in the photograph below, which allows unimpeded measuring, even in the case of long workpieces.

System Expandability (Option)

Roughness measuring detector (option)

In case roughness measurement capability is required following installation, the system can be upgraded to a multi-functional contour and roughness measurement system simply by adding a roughness detector and roughness analysis program.


Example of Ball Screw Measurement (Option)

Various evaluations are performed by dropping a sample circle on the ball screw grooves to obtain the point of contact between the sample circle and the profile.
