StrainMatic®
Imaging Polarimeters
Function
Automatic and Objective Measurement of the
Stress Birefringence in Glass and Plastics
and other Translucent Materials
Features
and
Benefits
- Automatic determination and color-coded presentation of the stress distribution
- Objective results, fast and easy operation
- Improvement in quality by on-site measurement
- Traceability by automatic filing of all parameters and results
- Cost reduction by optimization of the production process
Applications
- Optical materials and components (stress birefringence, homogeneity, micro-defects)
- Container glass (annealing lehr optimization, energy saving)
- Lighting (residual stress, glass metal transition)
- Tubing and pharmaceutical glass (residual stress)
- Plastic films (workability, polarization)
