Jewelry Binocular Microscope FGM-R5S-08


The microscope is a great tool for separating natural from synthetic, imitation and assembled gemstone and for quality grading of both diamonds and colored stone. The Model of FGM-R5S-08 is a swing arm Trinocular stereoscopic continuous zoom microscope, with Fable 5th generation Base can be rotated 360°,the lens can form a flat image with good contrast in the ultra-wide field of view, and the image at the edge of the field of view is also clear and bright, comparable to the imported OLYMPUS stereo microscope SZ61;

Provide four lighting modes,with high-quality dark field  
Cross-polarized conoscopic system
Magnification: 10X-67.5X
Zoom Ratio: 6.7:1
Integrated global wide voltage power supply with stable brightness.
Triocular lens,which can be connected with CCD

1.Check the surface characteristics of the gemstone. The surface of the gemstone is scratched, etched, damaged, bond surface (bubble, gloss difference), double crystal pattern, triangle growth mark, growth pattern, growth ribbon and so on.

2.Observe the internal characteristics of the gem, including the type, shape, quantity, double crystal plane, growth pattern, color distribution characteristics of inclusions, etc., for those with special inclusions.

3.Observe the interferogram

Use two polarizers to make them orthogonal, and install an interference ball at the position of the tweezers installation hole to provide conoscopic light, which can check the interference pattern of gems;

4.Check gem pleochroism

Just add a polarizer under the gem, you can only see one color at a time when you turn the gem, and it is better to turn the gem quickly for contrast observation;
