Glass Surface Stress Measurement Systems

Procured from Strainoptic Technologies, Inc., the highly efficient range of Non-Destructive Surface Stress Measurement Systems are widely demanded for measuring surface stress in tempered, heat-strengthened and annealed glass.

Surface stress is measured for process control of:

• Annealed Glass: to assure proper annealing and good cutting properties
• Heat-Strengthened and Tempered Glass: to meet product strength specifications
• Safety Glass: to validate tempering furnace settings for the desired break pattern or fragment size, which directly correlate to surface stress
