Stress Birefringence System WPA Series

WPA Series is PhotoNic Lattic's proprietary photonic crystal technology has developed a high-precision stress birefringence detection device, capable of measuring phase differences (optical path differences) up to 3500nm. It is suitable for stress birefringence detection of transparent components in injection molding, and its fast measurement capability is favored by major optical manufacturers and research institutions. It provides the stress birefringence size and distribution information of the tested product in seconds.
