Description

Technical Field

[0001] The utility model relates to the field of popular science and experimental technology of gem polarization phenomenon display, in particular to a gem polarization phenomenon display device. Background Art

[0002] Gems are the essence of nature. Because of their rarity, they are mysterious to the world, and the exploration of gems is endless. Gems are precious, rare, and indestructible. Most gem identification instruments are non-destructive spectral or optical instruments. Since most gems are transparent and suitable for light transmission, different types of light will produce different phenomena after passing through different types of gems. Gemologists classify and identify these phenomena, providing a scientific basis for subsequent gem identification.

[0003] Most gemstones in nature are crystals or composed of crystals. Each gemstone mineral crystal has its own individual characteristics and usually exhibits typical regular geometric shapes and different optical properties. According to the different optical properties, gemstone minerals are divided into two categories: homogeneous and inhomogeneous. Among them, homogeneous gemstones have the same optical properties in all directions, such as diamond, garnet, spinel, glass, etc., and inhomogeneous gemstones have optical properties that vary with direction, such as crystal, ruby, sapphire, peridot, etc. Polarized light refers to the conversion of natural light into light waves that vibrate in a fixed direction after passing through a polarizer. When the vibration directions of the two polarizers are perpendicular, it is a complete polarization effect, that is, orthogonal polarization, and the field of view is completely black. Placing homogeneous gemstones and inhomogeneous gemstones under orthogonal polarization will produce different phenomena due to their different optical properties.

[0004] However, the devices used in the prior art for teaching and demonstrating the polarization phenomenon of gemstones are either too complicated and expensive, or too simple in structure, and the display and adjustment operations are cumbersome.
