How does Sapphire Domes Differ from Ordinary Glass?
As a Sapphire Optical Components China , share with you. (1) Laboratory method: The detection of Sapphire Domes is very similar to the identification of jewelry, and the same equipment is used. The more commonly used instrument for jewelry identification is the refractometer, which can determine the refractive index of the object being tested. Although sapphire glass is artificial, But its refractive index is the same as natural, both 1.76 ~ 1.77, because sapphire glass is crystalline, so it has a heavy refractive index like crystal, which is 0.008. During the inspection, rotate and observe the polarizer on the eyepiece. It can be seen very clearly. The flat glass is better to observe, the spherical surface is not very good, and the refractive oil needs to be applied when testing. The refractive index of mineral glass is about 1.52, it is easy to distinguish it from sapphire, and it There is also no refraction. Sapphire Windows Another method is to use a polarizer. Any cr
