The Photron Crysta is a high-speed polarization camera for the two-dimensional analysis of birefringence measurements, film thickness analysis, and surface roughness inspection, and is a  powerful tool to understand phenomena such as birefringence, retardation, stress and impact fracture mechanisms of materials and fluids.

The PA and WPA systems provide the perfect means to resolve very low levels of residual stress in transparent materials such as glass, acrylic, polymers, etc.
