Depending on application we use three grades of CVD - ZnSe with different optical properties. There is no difference in transmission at 8 mm and above (see Fig.1).

Graph 1. Transmission spectrum of CVD - ZnSe window thickness of 10 mm.

	G 1	G 2	G 3
Absorption index @ 10.6 mm, less than, 1/cm	(5 - 8) x 10 - 4	1 x 10 -3	5 x 10 -3
Damage threshold, not less than, kW/cm2	2 - 3	-	-

CVD - ZnSe blanks are available in diameters 2 - 200 mm with thickness to 15 - 20 mm.
