L/W = 1.000 T/W = 0.184 T/L = 0.184 P/W = 0.405 C/W = 0.418
H/W = (P+C)/W+0.02 = 0.843 P/H = 0.480 C/H = 0.496
Vol./W^3 = 0.315

CROWN
Addition # 13 - Cut this in refractive indexes 1.62 to 2.14 with no changes. This is simple to cut and makes a very interesting design. I designed this for pale to light saturated material.
