Vector Optical Extensometer

With its real-time on-board processing capabilities, the Vector Optical Extensometer minimizes the time and effort spent on setup, easily producing accurate data within minutes of mounting it to any MTS load frame. Its integrated measurement head combines a stereo camera system and low-glare cross-polarized blue lights for optimal imaging and analysis.

Key Features & Benefits

  • Set up in Seconds — Automatic mark detection, no manual configuration
  • TestSuite™ TW EM Integration — Embedded setup interface for Criterion EM systems
  • Built-In Alignment Lasers — Visual positioning guidance
  • Validation Wizard — Pre-test accuracy check against ASTM E83 / ISO 9513
