Notes and Changes:

v1: REDLINE of D080050 (G.Billingsley, May'19)
v2: updated formal CAD drawing for review (R.JONES, Jan'20) Change Thickness tolerance to symmetric to prevent delivery of minimum allowing only 1.2 mm per surface for final polish/shape. The symmetric tolerance would allow 1.5 mm per surface (at the thick end) for final polish/shape. Based on current BS center thickness of 60.16 mm and current BS wedge of 0.079 °. Final polish design must account for best duplication of existing beamsplitter properties. - GB
