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:
•t Tensile, compression and flexure tests on metals and
plastics
•t From tests on micro-specimens with micro-strains to
testing specimens with a large initial gage length and
large strain
•t Tests on components and subassemblies
•t 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.
•t Tests in temperature chambers
•t High temperature tests
•t Where non contact biaxial strain measurement is
necessary

High measuring range, precision and resolution
•t The laserXtens Array features a very large measuring
range
•t The laserXtens Array provides high precision in micro
and macro measurement ranges
•t The resolution is 0.15 µm
•t The laserXtens Array meets or exceeds class 1 of
ISO 9513 (Class B2 of ASTM E83).

No specimen contact, no specimen markings
•t The laserXtens makes no contact with the specimen
and there is no influence on the test caused by the
laser light
•t The laserXtens does not require specimen markings
which results in several advantages:
t Saving of time especially at high specimen
throughput
t Simple use in temperature chambers
t 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
•t The laserXtens Array has no moving parts and is
completely free from wear
•t Different gage lengths are set in fractions of a second.
•t Measurement of transverse strain or flexion without
the need of additional specimen marks or hardware
extensions for the system (software option)
•t Measurement of r&n values on metals according to
ISO 10113 and ISO 10275 via option
•t 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)
•t Determination of the strain distribution and the strain
at break according to ISO 6892-1 annex H
