The optical extensometer for small specimens
The laserXtens 1-15 HP is the specialist for small specimens. It provides highly accurate, non-contact measurements of deformations in a measurement range up to 14 mm from a measurement length of 3 mm, without the need for gauge marks.
- The laserXtens does not require specimen markings, which is particularly beneficial in the case of small specimens. This saves both time and money.
- A telecentric lens compensates for lateral specimen movements.
- Measurements on specimens with a width/diameter starting at 1 mm, and even smaller after pretesting.
