GemCad Ray Traces for RI = 2.37, Zero Tilt Random Model Cosine Model ISO Model

GemCad Ray Traces for RI = 2.37, 20° X-Y Tilt Random Model Cosine Model ISO Model

Sphaler8 Designed by Jerry L. Capps 8-22-00 capdzinz@network2010.net
Order of brightness: CZ, Sphalerite, Corundum (with emphasis on tilt brightness)
Angles for R.I. = 2.37	57 facets + 16 facets on girdle = 73
4-fold, mirror-image symmetry	96 index
L/W = 1.000 T/W = 0.501 T/L = 0.501 P/W = 0.422 C/W = 0.159	H/W = (P+C)/W+0.02 = 0.602 P/H = 0.702 C/H = 0.264
Vol./W^3 = 0.216	Brightness at 0 degrees tilt for RI = 2.37 COS = 54.4 ISO = 74.8
	Brightness at 20 degrees X-Y tilt for RI = 2.37 COS = 52.1 ISO = 79.4
