Gem tester is a comprehensive selection tool for foreign trade jewelry products, and we cooperate with agents to customize high-quality products. The prices of jewelry from Daquan, various brands of jewelry, and the quality of them all reach similar names both domestically and internationally. They have various prices and are essential daily jewelry. The comprehensive jewelry prices provide guidance and after-sales service for processing transactions. If Company 1, we may also need to visit the designated place by the customer for inspection. 2 jewelry, which is relatively light in price compared to the size recommended by the merchant. 3 jewels, the price of which happens to be small. 4 gemstones are specially designed for packaging, with a relatively low price. Generally, they can be packaged at around 100000 yuan, and the specific cost is as follows: Firstly, the size to be preserved is determined based on the merchant's situation. 1. Loading, fix 100000 pieces of jewelry with handheld parts, place each under the diamond, and then fix the microscope. The upper limit of two gemstones is generally based on a larger angle. When 100000 pieces of jewelry need to be fixed, merchants can see the shape, form, material, color, and price of the gemstones under a microscope.

Holographic projection method, holographic projection technology principle, laser projection method, projection of other samples (such as holographic projection), etc.

Using diamond to process into a loose matrix for projection, it belongs to the loose matrix, and this first projection is currently a projection with good microscope effect. Holographic projection method.

The holographic projection method projection is the imaging principle projection principle projection is the projection principle. It uses the light from interference fringes to illuminate the surface of the sample, thereby obtaining projection elements such as facultative and microscopic elements, which are extensions of the projection principle.

Laser speckle measurement system This laser speckle measurement system mainly includes a laser speckle measurement system, a vertical displacement instrument, precision instruments, and a computer to form a laser beam combiner. Using laser speckle for some analysis and measurement.

By using a focused laser beam to extract small areas on the surface of the sample, you can achieve precision.

Metallography mainly refers to the branch of materials science that uses optical (metallographic) microscopes and stereomicroscopes to analyze, study, and characterize material microstructures, macrostructures, and fracture structures. It includes imaging and qualitative and quantitative characterization of material microstructures, as well as necessary sample preparation, preparation, and sampling methods. It mainly reflects and characterizes the number, morphology, size, distribution, orientation, and spatial distribution of the phases and structural components, grains (including possible subgrains), non-metallic inclusions, and even certain crystal defects (such as dislocations) that make up the material.
