Test the refractive index and the bigest double refractive index of the big and level facet gemstones
Many gemstones are double refraction(birefringence) on optical character. For the gemstones,you must test and get its minimum and maxinum refractive index ,and their margin,so this instrumentcan give a accuracy reference for identifing gemstones.
As long as you obey the step,you can obtian the above mentioned data on any level facet. Revolve the gemstone and get two data on each place is the most important steps below.Users who are not familiar with the principle above, Please consult the relevant books.
