Spectroscope FPS-3

Spectroscope Model: FPS-3 Instrument: Due to the white gem selective absorption, when white light through a gem, certain wavelengths of light are absorbed, can be observed with a spectroscope. The selective absorption of gems, the type of color elements related to its cause. Thus, the color of spectroscope is to identify genuine and fake gems most powerful instrument. In addition, many gemstones having a characteristic absorption spectrum, this spectrum is observed, it can determine the type of gemstone. For example, rubies, almandine, emerald, zircon, jade, peridot, gold emerald. FPS-3 type prism spectroscope, using high-quality triple prism having a good light, high resolution, easy operation ★ prism, broad spectrum, high resolution; ★ fixed slit, fixed focal length ★ black frosted shell, feel good while avoiding interference of reflected light; ★ leather-wrapped Close Fable handheld prism spectroscope Model: FPS-3 Features Introduction other ★ prism, broad spectrum, high resolution; ★ fixed slit, Fixed focal length ★ black frosted shell, feel good while avoiding interference of reflected light; ★ leather-wrapped gemstone due to selective absorption of white light, white light through a gem when certain wavelengths of light are absorbed, can be observed with a spectroscope .

FPS-3 type prism spectroscope, using high-quality triple prism having a good light, high resolution, easy operation prism beam splitter features 1) a blue-violet region of the spectrum is relatively widened the red zone Relative compression 2) translucent, and can produce some bright spectrum 3) red region is relatively poor resolution perspective: for transparent to translucent gem L 1) wipe gems, precious stones placed in the cold light of the above so that the light through the gem 2) will be viewed through a spectroscope aligned gem light part 3) to adjust the angle of the beam splitter (including slit or focus until see the spectrum so far) internal reflection law: for light color, small particles transparent gem 1) Clean gem, the light from an angle gemstone obliquely upward into the goal, and it reflected from the other side of the stone 2) directly at the reflected light beam splitter 3) Adjust the angle of the beam splitter (including slits or focal length to see the spectrum until last) surface reflection law: for opaque or poor transparency gem 1) Clean-precious stones, so that the light reflected from the sample surface out of 2) out of the light beam splitter aligned 3) Adjust the spectroscope gem name angle (including slit or focus until the date to see the spectrum) spectroscope uses U 1) can be determined with typical spectrum: Zircon 653.5nm absorption lines typical diamond 415.5nm 2) help distinguish certain natural gemstones and synthetic stones : natural blue spinel, which was complicated Spectral synthesis, cobalt spectrum 3) help distinguish some very natural gemstones and artificial process gem: natural green jade, red light district at 630-690nm was three stepped absorption bands, staining Emerald red light district was vague absorption band 4) help distinguish some gems and imitation: ruby ??red glass was chrome spectrum and spectrum was rare, emerald green gadolinium was chromium spectrum and can significantly rare earth aluminum garnet spectrum 5) to help determine the gem The coloring element: Ruby was chrome spectrum, olivine was Ferrography, CZ was rare spectral characteristics of the dichroic mirror Z 1) Identification little gem made conclusive but can provide a lot of research data 2) Ruby , emerald, sapphire is necessary to identify the content of 3) the biggest role in that process of elimination, removing many possibilities 4) should be combined with other instruments, make judgments gem common characteristic absorption spectrum C 2 Red Series: ruby, spinel, almandine, pyrope, glass 2 Yellow Series: diamonds, gold emerald, apatite, spessartine 2 Green Series: emerald, peridot, boron aluminum garnet, emerald, emerald 2 blue staining Color Series: sapphire, spinel, synthetic spinel, glass 2 colorless Series: diamonds, zircon, enstatite 2 Other: alexandrite, synthetic corundum, imitation alexandrite, turquoise
