L/W = 1.000 T/W = 0.350 T/L = 0.350
P/W = 0.383 C/W = 0.205
H/W = (P+C)/W+0.02 = 0.608
P/H = 0.631 C/H = 0.337
Vol./W^3 = 0.186
Addition # 8 - Cut this in refractive indexes 1.62 to 2.14 with no changes. This design is not quite round but it will fit in a round setting. It looks interesting when cut. This works well in about any material.
