Stress Photonics provides a wide range of inspection tools to examine automotive sidelite/backlite
The EdgeMaster 2 is a very useful tool for edge stress measurement of tempered glass products. This real-time inspection system with integrated edge guide is easy to use. The system is hand-held and specifically designed to slide along the edge of a sidelite, backlite, windshield, or sunroof. When imaging a windshield, backlite, or sunroof, the system can reflect light off black frit to measure edge stress. These measurements can be logged at key locations. There are some limits with darker tinted glass. Contact our team of experts for details.
The GFP1600 REFLECT (GFP1600 with reflection illuminators) can also measure stress on the frit, including edge stress. Because it’s a more general purpose instrument, more set-up may be required.
The GFP1600 FPI (Flat-Panel Illuminator) is an excellent tool for measuring temper patterns. The system measures the average stress through the glass and can show the imbalance in tempering, although it does not explicitly provide the surface (skin) stress.
For thermal stress, the GFP 1600 FPI (Flat Panel Illuminator) is quick enough to monitor slower transient thermal stress events like those induced by window defrosters and wiper heaters. The system can be equipped with any c-mount lens, including zoom lenses, to conveniently image broad areas and/or close-up details. The temper pattern can be removed during processing to isolate the thermal stress, showing only the change.
For faster thermal transients, the GFP2600 real-time inspection system can be used to acquire stress videos. The GFP2600 is small and nimble, but the integrated fixed focal length lens requires more setup changes to acquire a range of field-of-views.
Some assembly stress work can be accomplished by viewing the changes in stress in the glass; however, often it’s important to know the stress changes on the outside surface caused by bending. The GFP1600, combined with simple glue on sheet coatings and a camera jig, is an ideal tool for measuring assembly stress. Sheet coatings are easy to apply, and the glass stand accurately positions the system over the coating, without fuss.
