Gem Testing Instruments Gemology Stander Conoscope for Polariscope
Model:FTP-ZG
Description:
In gemology, we use a conoscope (a strain free acrylic or glass
sphere on a rod) to determine optic character (uniaxial or biaxial)
in anisotropic gemstones. The conoscope creates a 2-dimensional
image of the 3-dimensional interference in a mineral.
Although determining the optic character with a conoscope is a
fairly easy procedure, finding the interference figure itself is
not. The interference figures always appear around the optic axes
of minerals.
The simplest way to find an interference figure is to rotate the
stone under the polariscope, in every possible direction, while
looking down the analyzer until one sees a small flash of colors
appear on the surface of the gemstone. When that flash of colors is
found, fix the stone in that position and hover your conoscope
slightly over it. Now, while still looking through the analyzer,
you should see the color flash transform into a rounded
2-dimensional image.
This image in uniaxial stones will appear different from the image
in biaxial stones, each having its own characteristic pattern.
Applications: Gemological Laboratory, Gemology school, Jewelry industrial
