Gem tester foreign traders, you can no longer wait to understand its Ming Dynasty mysteries. Using ultraviolet rays to provide their ideal solution for your mysteries and understand the parameters of different types of gemstones.

Usually, the electron beam of a gemstone is an electromagnetic chip that is amplified and imaged. It is excited by a magnetic field to generate electron emission, which is transmitted to the analysis system through a vacuum system. Then, the electron beam is illuminated point by point on the sample surface through an image display, obtaining a high-resolution image of the surface.

By drawing or using graphical methods, the surface feature information of gemstones can be accurately measured and converted into digital signals, and the periodic mean of each pixel can be calculated through metrology.

Optional digital microscope, using high-precision optical components, ensures that the magnification can be continuously adjusted within the complete magnification range to obtain high-resolution images such as pixels.

Optional attachment: In order to break through the influence of the microscope on the image plane created by optics, the resolution of the instrument can be reduced to 1/100 times, and the instrument adopts a parallel beam constrained by a parallel light diffraction cone with high magnification, reducing the magnification of the instrument and ensuring the resolution of the system. In addition, the instrument also has high resolution ability, which can easily quantify the image from the details of lens imaging, and has high contrast cylindrical angle and phase matched aberration in terms of refractive index.

Suitable for various microscope imaging and inspection, analysis and filtering of surfaces, mathematical particles, grains, scratches, and particle analysis, amplitude and comparison, failure analysis of IV curves. The selection of optical microscope imaging should be quantified based on the imaging details. Generally, optical microscopes should leave a distance to ensure the clarity of imaging and the clarity of distinguishing targets.

What are the classifications of metallographic microscopes and the above two: optical microscopes are used for high-resolution and deep characterization of the macroscopic surface of samples, such as observing the surface morphology and structural characteristics of samples, and conducting necessary analysis; Tokyo Instrument Desktop Metallographic Microscope.

The reflective metallographic microscope is equipped with a falling beam illumination, flat field objective, and large field eyepiece, with clear images and good contrast. At the same time, it is equipped with a polarizing device to achieve polarized observation, corresponding to basic measurement functions such as objective magnification and field of view range.

Inverted metallographic microscope is mainly used to identify and analyze the internal structure and organization of existing metals. Inverted metallographic microscope is an important instrument for studying metallography in metallurgy. Casting. Quality research on smelting and heat treatment, inspection of raw materials, or analysis after material treatment can all be conducted using an inverted metallographic microscope
