Description

Multi-person real-time visualization gem polarizer

technical field

The invention relates to a gemstone polarizer, in particular to a gemstone polarizer with real-time visualization by multiple people.

Background technique

Gem polarizer is a non-destructive identification instrument used to detect the homogeneity of gemstones, judge the axiality of gemstones, and observe the pleochroism of gemstones. The main components of the gemstone polarizer are the upper and lower polarizers and the light source. When the polarizer is designed, the lower polarizer is usually fixed, and the upper polarizer can be rotated to adjust the polarization direction. When natural light passes through the lower polarizer, polarized light is generated. If the directions of the upper and lower polarizers are parallel, all the polarized light from the lower polarizer will pass through, and the brightness of the field of view will be maximum; if the directions of the upper and lower polarizers are perpendicular, the polarization from the lower polarizer will All light is blocked, and the field of view is the darkest at this time, that is, extinction occurs. Gemstone polarizers are precision instruments, which have high requirements for shockproof, dustproof and anti-interference. Since the gemstone polarizer requires the user to observe from the vertical top of the upper polarizer, it is not suitable for multiple people to use at the same time, which leads to the limitation of real-time phenomenon observation. In the field of teaching, the above gemstone polarizers have shortcomings such as time-consuming observation of experimental results and inconvenient explanation and analysis.
