the polariscope is a critical piece of equipment for any gemologist39s office. it can easily identify single and double refractive gemstones and in many cases allow you to view the optic interference figure and give you the optic character of the gemstone. too large and difficult for travel but on the desk of a properly trained gemologist the
alibaba.com offers 221 polariscope products. about 31 of these are jewelry tools amp equipment 15 are other optics instruments and 7 are testing equipment. a wide variety of polariscope options are available to you such as loupes magnifiers testers amp measurements and tweezers pickup tools.
the polariscope may be one of the most underestimated tools in gemology. most gemologists use it to quickly determine if the stone at hand is isotropic or anisotropic or at best to determine the optic character of gemstones. with some small additions one can determine both optic character and the optic sign of a gemstone.
a polariscope consists of a light source and two crossed polarized lenses. the light source which is powered by batteries within the polariscope or an external energy source is placed between one of these lenses.
photoelasticity describes changes in the optical properties of a material under mechanical deformation. it is a property of all dielectric media and is often used to experimentally determine the stress distribution in a material where it gives a picture of stress distributions around discontinuities in materials. photoelastic experiments also informally referred to as photoelasticity are an
equipment. a polarimeter is the basic scientific instrument used to make these measurements although this term is rarely used to describe a polarimetry process performed by a computer such as is done in polarimetric synthetic aperture radar.
