1-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.443 T/L = 0.443 P/W = 0.442
C/W = 0.167 H/W = (P+C)/W+0.02 = 0.628 P/H = 0.703 C/H = 0.265 Vol./W^3 = 0.192

 

Addition # 11 – Cut this in refractive indexes 1.54 to 2.14 with no changes. This is actually designed for single color non-shiller material or light watermelons. Note: The table is not large so it works best in pale colors.
