Abstract (en)
[origin: WO2004059266A2] The disclosure is directed to precise measurement of out-of-plane birefringence properties of samples of transparent optical material. Two angled-apart light beams are passed through a selected location of a sample optical element. One of the beams is incident to the sample surface. The characteristics of the beams are detected after passing through the sample, and the information detected is processed to determine the out-of-plane birefringence.
