... and the program POLARIO ( Fischer et al . 2018 ), is 1.507. For the sake of comparison, the same approach was used to calculate n D = 1.511 for lalondeite, which agrees well with the average n D = 1.526 calculated from the measured refractive indices ( McDonald & Chao 2009 ). Kodamaite is length slow...
