FAQ
Frequently Asked Questions
No. While both involve polarized light, a dichroscope is specifically designed to show the two different colours (dichroism or pleochroism) of a gemstone simultaneously. A polariscope primarily detects strain and optical character (isotropic vs anisotropic).
Primarily professional gemologists, mineralogists, and serious gem collectors for identifying and studying gemstones and minerals.
No. It is a diagnostic tool primarily useful for anisotropic (doubly refractive) gemstones that exhibit pleochroism. Isotropic gems like diamond and garnet (spinel-type) will not show two colours in a dichroscope.
It comes from the Greek 'dichroos', meaning 'two-coloured' ('di-' = two, 'chroa' = colour).
