A World First


The LTS-640V boasts the fidelity of a high-end R&D instrument with the ruggedness, versatility and ease-of-use of an industrial tool.


Applications include: 

  • Validation of structural FEA (Finite Element Analysis)
  • Identification of areas of structural weakness
  • Structural health monitoring
  • Detection, monitoring and characterisation of fatigue cracks
  • Non-Destructive Inspection (NDI)
  • Research and teaching in structural mechanics

Advanced Stress Imaging, Simplified


With an ultimate stress sensitivity of < 1 MPa1, the 1MILLIKELVIN LTS-640V has ample precision for the most demanding of applications, but none of the complexity you might expect. Getting started is a matter of ‘plug and play’.


The in-built visual sensor along with the visual-stress fusion function allows for easy identification and location of critical stress regions.

MiTE Suite


Packaged with all systems is the powerful MiTE Suite software package, providing:

  • Full complex-valued thermoelastic response 
  • Real-time display for Visual and Infrared
  • Semi real-time display (user selectable frame rate) for Stress and Stress-Visual Fusion 
  • Real-time stress monitoring for damage detection and trend analysis
  • Plotting functions
  • Point and ROI metrics
  • Stress and strain calibrations
