\nThe SBR-01 is based on the Senarmont method, which is one of the most popular birefringence measurement methods. The Senarmont method is adopted as the standard method for glass strain (birefringence) measurement by the Optical Glass Manufacturers’ Association of Japan. This optical measurement principle is also known to be less prone to measurement errors than other measurement principles in terms of alignment errors of the optical elements used in the measurement.
