Design of Pressure Window

Minimum thickness of a window required to withstand a pressure differential can be calculated by the following formula:
Th =
Th = thickness, inches
DIA = unsupported diameter, inches
P = pressure differential, psi
MR = modulus of rupture, psi 
Modulus of rupture (MR, psi) of commonly used crystals:
