n: Refractive IndexKH: Knoop HardnessMOR: Rupture Modulus

†The apparent elastic limit is reported for those materials which permanently bend prior to rupturing.

*The modulus of rupture (MOR), m, determines the size of the window needed to withstand a pressure, p.

For a four times safety factor, the thickness of a mounted window, t, with an unsupported diameter, d, is:

 

tclamped = 0.866 d (p/m)1/2

 

tunclamped = 1.05 d (p/m)1/2
