laserXtens extensometer

laserXtens and laserXtens HP extensometers

The measuring head consists of two cameras mounted on motorized slide carriages, allowing the distance between the cameras to be varied so that different initial gage lengths can be set.

Advantages of laserXtens

  • The laserXtens HP extensometer can be used for strain-controlled tests to ISO 6892-1 Method A1 (closed loop). Suitable for gage lengths
    ≥ 50 mm.
  • laserXtens satisfies the requirements of Class 1 (0.5 for laserXtens HP) of ISO 9513 (Class B2 of ASTM E83).
  • Resolution is 0.15 μm (0.11 μm for laserXtens HP).
  • laserXtens can also be used for simultaneous measurement of axial strain and torsion.

laserXtens systems

Extensometers using laserXtens systems provide non-contact measurement of deformations on a wide range of materials. They consist of measuring heads with digital cameras and laser light-sources. The specimen is illuminated with laser light, generating a speckle pattern on the surface. When the specimen is subjected to a load the virtual gage marks are displaced and the evaluation windows are updated. laserXtens calculates the strain on the specimen from the displacement between two consecutively recorded images.

Advantages of laserXtens

  • laserXtens systems deliver high precision in the micro and macro measurement ranges.
  • Measuring principle eliminates the need to apply gage marks.
  • laserXtens can be mounted at varying distances from the specimen. A key advantage of this is that it can be used in temperature chambers.
  • In contrast to contact extensometers or pure video solutions, laserXtens systems can measure strain on short specimens (gage lengths from 1.5mm) with high accuracy.
  • laserXtens is integrated into testXpert II. Use of a separate 22“ monitor is recommended to enable the live image from laserXtens to be observed parallel to the testXpert II display.
