L/W = 1.936 T/W = 1.520 T/L = 0.785 P/W = 0.458
C/W = 0.177 H/W = (P+C)/W+0.02 = 0.654 P/H = 0.700 C/H = 0.270 Vol./W^3 = 0.466
Cut this in refractive indexes 1.54 to 2.14 with no changes. This is designed for shiler or color. Note: A preform of the correct L/W is the best way to cut this. The P4(G), P5(G) are equal size. L/W is not critical, but this design not for a beginner.
