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 WPA-Kamakiri Wide-Range Birefringence Measurement System provides the perfect means to resolve very low levels of residual stress in transparent materials such as glass, acrylic, polymers, etc.
