Pyroxene Visible Spectra (generally 350 - 2500 nm)

polarizations: (a = alpha direction; b = beta direction; g = gamma direction) 

Pictures of pyroxenes showing the pleochroism

        Enstatite polarized parallel to the c-axis; two crystals, one from Tanzania, the other from Myanmar
        Enstatite polairzed parallel to the b-axis
        Both, compared side-by-side.                           T
