Note: 1.The refractive index is a very important optical parameter. The gloss of gems the can be determined by this parameter. Since different have a fixed refractive index, all kinds of gems can be determined according to the refractive index. Birefringence can also be measured. This parameter can be used to determine whether a gems is uniaxial or biaxial. 2.Shipped with liquid, shipped without battery.
