Ade Advanced Optics Gemological Gemstone Gem Refractometer Built-In Light for GIA testing






























GEMOLOGICAL GEMSTONE GEM REFRACTOMETER BUILT-IN LIGHT

This refractometer requires RI oil. We sell it separately, please CLICK HERE for the RI Oil

This item is commonly known as Gemstone Refractometer, is the primary and most powerful tool in identifying and authenticating polished precious and semiprecious gemstones and also observing the optical properties and the structure of gemstones. This model is just as good as the expensive models used in gemological institutes, it has a built-in light source and with the aid of the Contact liquid (RI Fluid), which creates an optical contact between the glass and the gemstone, you can measure or test the Refractive Index of faceted stones, its transparency or opacity, and its beauty, durability and scarcity.

The refractive index (RI) of a gemstone provides the single most important piece of information to a gemologist seeking to identify an unknown stone. Due to its chemical composition and crystallization structure, each gem has a typical refractive index. In fact, you can also use this tool to measure R.I. for many minerals in crystal form as long as the crystals have a flat and polished face. Through these parameters, you can determine whether the gem is a Single Refraction (Isotropic) or Double Refraction (Anisotropic or Birefringence).

This product offers you the worry-free, light and easy way to identify and/or authenticate your most precious gemstones.

Features:
  • Convenient & easy to carry
  • With built-in light source that makes it a carry-and-use-it-anywhere device
  • Comes with Automatic Temperature Compensation (ATC) that let itself adjust to the climate
  • Approved by strict quality and safety standards
  • Undoubtedly durable and very reliable
  • Two color available, black and light grey. Black color will be the default color to ship.

Specifications:

  • Measuring Range: 1.30 – 1.81 RI
  • Minimum Graduation (RI): 0.01 RI
  • Illumination: Internal illumination with momentary switch(Standard wavelenth 589nm)
  • Size: 30mm x 70mm x 130mm
  • Scale Division: 0.01 nD
  • Weight: 0.4 kg

Operating Information:

  • Open the upper cover then wash the gem and prism with alcohol.
  • Lay the instrument on the worktable. Drop a little bit of special refractive oil onto the surface of prism and press it by a thin glass bar. (Be sure not too much or too little)
  • Make sure the ground surface of gem to be measured is close to the prism, press it again lightly, let the refractive oil be evenly distributed between the two surfaces then close the upper cover.
  • Press the light momentary switch, make sure that the internal light source is turned on when testing.
  • Move the eyepiece up and down and adjust the diopter accordingly. By this time you can see a light/dark boundary in the viewing field. The gradation (shade) on which the boundary located is called the refractive index of gem.
