The glass stress tester enables quick visualisation and assessment of the stress introduced into the glass
The optical glass stress tester visualises stresses in glass through interference colours. It is suitable for all common transparent glass types including quartz glass. The maximum distance between polariser and analyser is approx. 10 cm. Note: This is an imaging procedure for the qualitative assessment of the glass, no exact measurement takes place.
Your Advantages
Fast quality control of glass samples
Simple assessment of stress input and fracture behaviour
