To See Large Sample Stage for LCD-Substrate Click Here. Model ABR-10A is a measuring equipment for linear birefringence with high resolution of 0.01nm. You can measure both the retardation and principal axis direction simultaneously.
Birefringence is indicated on the basis of optical phase difference.
Each measuring point has approximately 1 second sampling time. The interferometer is almost free of maintenance in the long run. Because it has simple optical system with few optical components. Scanning the sample stage makes it possible to draw two-dimensional distribution maps of birefringence. With enough parameters measured, you can also see the analysis-result at a glance.
