Raw optical glass. Determination of birefringence1 Scope This International Standard describes the stress optical method for determining the birefringence in glass, especially in raw optical glass in bulk and preshaped forms. This method is also used in photo elasticity. NOTES 1 The calculation of the elastomechanical stress from the birefringence is not the subject of this International Standard. 2 The indication on the drawings of birefringence is specified in ISO 10110 2 (see reference [2] in

— the nipples specified in Annex B of ISO 172561)
