Contactless Optical Extensometer

The optical extensometer uses a high-resolution video acquisition system to measure specimen deformation without any mechanical contact. It is ideal for brittle, reactive materials, or materials that deform in an unstable manner.

Optical measurement is based on markers applied to the specimen (points or lines) and can be performed with gauge lengths from 20 to 100 mm. The analysis is continuous and enables precise monitoring even at high strain rates.

Highly valued in research labs, R&D centers, and the biomedical and aerospace sectors, the optical extensometer ensures reliability, zero interference, and compatibility with all latest-generation Acquati dynamometers.
