laserXtens 1-15 HP exensometer

The laserXtens 1-15 HP is a high-accuracy testing system for testing small and very small specimens. Therefore, in addition to a camera and two laser light sources, it also has a special lens. This is because a telecentric lens can compensate for lateral specimen movements (see below).

Due to the short distance to the specimen, this laserXtens can be mounted only to the zwickiLine. It is not moved; it has no connection to the crosshead.

laserXtens 1-15 HP: Compensating for lateral specimen movements
With some specimens or test arrangements, the specimen is prone to moving out of the test axis. This is especially common with small specimens. A change in the specimen distance to the camera does however, in a trapezoidal field of view, result in an magnification/demagnification of the specimen, whereby the test results are influenced. The telecentric lens of the laserXtens 1-15 HP compensates for these lateral specimen movements and minimizes measurement error.
