Stress Photonics offers a wide range of glass stress imaging tools to inspect specialty glass for stress states such as:
The images below are of HVI (Hypervelocity Impact) defects created when small but extremely fast-moving space particles struck the space shuttle orbiter window in flight. The defects are characterized by loss of glass in a central pit, periphery fracture damage, the re‐fusing of glass, and the embedding of glass into the structure below causing a radial stress pattern. Subsurface cracks are not uncommon. They generally are close to plane‐parallel or make a slight angle with the surface.
