X-Sight ST Optical Extensometer (Semi-telecentric)
The ST is a compact, semi-telecentric optical extensometer engineered for high-precision strain and displacement measurements on small specimens. It is effective even in extreme testing environments. Its adjustable telecentric optics deliver exceptional measurement stability. In addition, they allow the field of view and working distance to be tailored to the application.
A high-resolution industrial camera, low-distortion optical path and monochromatic green illumination work together to produce clean, high-contrast images with micron-level accuracy. With optional high-temperature filters, the ST remains fully operational up to 1800 °C. These filters suppress specimen glow for crystal-clear results in demanding thermal conditions.
The lightweight design, integrated illumination module and robust mounting options enable fast setup on virtually any testing machine. When combined with seamless software integration through X-Sight Alpha DIC, the ST provides a reliable solution for advanced material testing workflows. This integration includes real-time data streaming, external triggering and flexible communication protocols.
