laserXtens Array: non-contact measurement in a large measuring range - 1

Product Information laserXtens Array: non-contact measurement in a large measuring range Applicational range The laserXtens Array can be used to measure strain or deformation on a wide range of materials. Using the latest laser speckle technology means that there is no contact with the specimen during the test and no need to attach marks. This enables the laserXtens to work in a wide range of applications: • Tensile, compression and flexure tests on metals and plastics • From tests on micro-specimens with micro-strains to testing specimens with a large initial gage length and large strain • Tests on components and subassemblies • Applications where a contact extensometer might be unsuitable due to its physical contact with the specimen and which might be damaged by the whiplash experienced at specimen failure. • Tests in temperature chambers • High temperature tests • Where non contact biaxial strain measurement is necessary High measuring range, precision and resolution • The laserXtens Array features a very large measuring range • The laserXtens Array provides high precision in micro and macro measurement ranges • The resolution is 0.15 µm • The laserXtens Array meets or exceeds class 1 of ISO 9513 (Class B2 of ASTM E83). No specimen contact, no specimen markings • The laserXtens makes no contact with the specimen and there is no influence on the test caused by the laser light • The laserXtens does not require specimen markings which results in several advantages: Saving of time especially at high specimen throughput Simple use in temperature chambers The system can plainly be used in robotic testing systems, as no manual specimen preparation is needed prior to the test Unrivaled functions and options • The laserXtens Array has no moving parts and is completely free from wear • Different gage lengths are set in fractions of a second. • Measurement of transverse strain or flexion without the need of additional specimen marks or hardware extensions for the system (software option) • Measurement of r&n values on metals according to ISO 10113 and ISO 10275 via option • Measurement in two dimensions, up to 100 measuring points in any desired configuration or arranged in matrix form on a plane specimen surface can be dimensioned (option 2D dot-matrix) • Determination of the strain distribution and the strain at break according to ISO 6892-1 annex H

laserXtens Array: non-contact measurement in a large measuring range - 2

Product Information laserXtens Array: non-contact measurement in a large measuring range Function description The speckle pattern can be thought of as a ‘virtual measuring mark’ or ‘digital fingerprint’ on the surface of the specimen and is monitored with full frame digital cameras. The laserXtens Array software tracks this virtual measuring mark in consecutive images taken during the test, and this procedure is called speckle tracking. Innovative, patented technology Unlike the standard laserXtens, on which two digital cameras mounted on motorized slides can be used to set different...

laserXtens Array: non-contact measurement in a large measuring range - 3

Product Information laserXtens Array: non-contact measurement in a large measuring range Software options Strain distribution The option strain distribution is used to determine localized strains at several measuring locations along the gage length on the specimen. The evaluation of up to 16 measurement marks is possible. In addition, a balancing of the beginning gage length can be performed in order to follow the necking-in automatically in real time (according to ISO 6892-1, annex H). Measurement of the deflection in 3- and 4-point flexure tests The laserXtens is also used for 3- and...
