Stress Birefringence System WPA Series

The 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 in transparent molding components for injection molding. Its fast and accurate measurement capabilities are highly favored by optical manufacturers and research institutions. It provides the stress birefringence size and distribution information of the tested product in seconds.
