This standard specifies a method for the measurement of the refractive index of crystals using the minimum deflection angle method at room temperature. Applicable to the refractive index test of crystals. The standard describes in detail the Measurement principles and test methods, taking into account the Optical inspection characteristics of different crystal systems such as isotropy, uniaxiality and biaxiality of crystals. Optical inspection characteristics provide guidance for accurate measurement of the refractive index of crystals.
