The existing observation method is to use a laser pointer to directly irradiate the outer surface of the sapphire crystal to observe, and the laser light will be reflected on the outer surface of the sapphire crystal. Because there is strong reflection when the laser pointer is directly irradiated on the outer surface of the sapphire crystal to observe, using the existing The observation and sorting method will not only hurt people's eyes, but also affect the observation effect

Abstract
The invention relates to a special device for observing and sorting air bubbles of a sapphire crystal with free-upward view and full view angle. The special device comprises a high-transparent glass container containing purified water, a lifting pulley, a buckling rope, a support frame and a plane mirror. The support frame is arranged below the high-transparent glass container; a support seam allowance hole for placing the high-transparent glass container is arranged at a center of a support panel of the support frame; the plane mirror is arranged at the bottom of the support frame and is in parallel with the bottom of the high-transparent glass container; and the lifting pulley is positioned above the high-transparent glass container. When laser irradiation is carried out on the surface of the crystal by people with a laser pen, laser penetrates through a wall body of the high-transparent glass container and the purified water and then irradiates the sapphire crystal. Observing and sorting the sapphire crystal by utilizing the device of the invention, the people are easy to better observe and sort the sapphire crystal and can carry out full angle observation of 360 degrees on the air bubbles in the sapphire crystal, and the people's eyes can not be hurt.
Description
Technical field: [0001] The invention relates to a crystal observation device, in particular to a bubble observation and sorting device in a sapphire crystal. technical background: [0002] Sapphire (sapphire) is Al 2 o 3 Single crystal, with high melting point (about 2050 ℃), high hardness, good thermal conductivity, wide light transmission band, good electrical insulation, strong acid and alkali corrosion resistance, etc. Currently producing large size Al 2 o 3 The methods of single crystal include kyropoulos method, pulling method, heat exchange method and flame fusion method, among which the most widely used and the most mature production technology is the kyropoulos method, but bubbles are also easily generated in the obtained sapphire single crystal, which greatly Large bubbles will form millimeter-scale cavities, and small bubbles will appear as a large number of cloud-like scattering particles. Whether there are bubbles in the sapphire crystal or not, the size of...
