Description:
The Polariscope is the fastest way to test the optical properties of gemstones,quickly determine whether translucent or transparent gems are singly or doubly refractive,resolve optic character in doubly refractive gems, spot pleochroism, and detect diamond strain. Opening at front can double as light source.Includes interference figure sphere(Conoscope).
It will tell you about a gemstone with ease. by simply holding the stone between the polaroid plates you can identify the stone as being double refractive (DR) or single refractive (SR), and whether a gem material has internal strain that could cause damage to a stone easily.

Feature:
Gemmologist tool for testing transparent gemstones
Observation of optical properties, glass strain, etc.
Built-in long life and high brightness "LED" light source.
Full visible light spectrum (400nm-700nm)
A CONOSCOPE included.
Detachable European style crocodile clip included, you can rotate the stone in any direction. With conoscope, you can get the interference figure with ease ! (interference figure help to define the optic axis.)
Adaptable plug for your country (if not, we will provide free adapter,Europe,South & North America,Africa,US,UK,Australia,Japan...)
With a table glass over the lower polarizer for place your gemstones.
A refractometer light source window on the front of the polariscope(non-monochromatic light)
